Buying Vintage Stereo Equipment
We, as do many, believe that the majority of amplifiers, receivers and turntables from the 1960’s and 1970’s are superior to the modern counterparts. Of course, you can buy some very fine equipment today that will equal or surpass it. The only catch is the cost will a great deal more.
It should be no surprise that to match a turntable that sold for around $150 in 1975, one would need to spend somewhere around $500 to $1000 for a comparable turntable today. Some vintage ‘tables would only be matched by modern counterparts costing thousands.
You could buy a new car in 1975 for about $3500, and a nice one for $6000. A nice home could be purchased for around $50,000. A good lunch could be had for around $2 to $3, and a dinner at a fine restaurant for around. It should be no surprise that a turntable purchased today for $100 will be of dubious quality.
Just found a vintage amp or receiver that has been untouched and untested for many years? DO NOT plug it in. You might get lucky, or you might destroy parts that cannot easily be replaced. It’s important to be aware that buying vintage gear in original condition, and expecting trouble free use from a component nearly half a century old, will no doubt lead to disappointment. Many of the turntables from this era, require relatively minimal service to bring them back to former glory. Amplifiers and receivers will much more extensive restoration. Buying such an amp or receiver should include a budget of at least a few hundred dollars for the necessary service. Double that for giants like the Pioneer SX-1250.
The equipment we sell in our shop has already undergone a restoration process.
First of all, and this is an important disticntion, a “turntable” (or a record deck for our european friends) is not a stand alone item. And amplifier and speakers must be supplied. A “record player” on the other hand, has all of this built into one box. Sometimes very large furniture enclosures, as with the consoles of the 1960’s.
It is important to note that most modern amps and receivers have no phono input. A cost cutting measure, as a phono input requires a significant number of additional parts. By the 1990’s, many manufacturers chose to spend the saved money on video capabilities, surround sound, and other “bells and whistles”. If you already have such an amplifier or receiver, a separate phono preamp device can be added at about $50 or more. A preamp on the order of what would be expected from a built in unit, will be around $100 or more.
Belt or direct drive?
A common source of confusion. Much of the main stream stereo industry held up direct drive as the best approach when it was introduced in the 1970’s. In fact, the majority of the cutting edge modern turntables are actually belt drive. In short, there are many fine examples of both. Belt drives turntables will eventually need a new belt, but in almost every case, this is easily replaced. Direct drive turntables require complex electronics to manage speed, and are more costly to service.
Automatic – Semi Auto – Manual
All turntables fall into one of these categories. A manual turntable requires you to move the arm over, and then retrieve the arm when the record ends. Most turntables have a cue lever that aids in lifting the arm. Semi automatics require you to move the arm over, but will automatically return it at the end. Fully automatic turntables can be operated without ever touching the tonearm. Technically there is a fourth version called a “changer”. These could play up to six records one after the other. Dual is probably the most respected and best example. No changers were produced after the early 1980’s. The vast majority of turntables sold today are fully manual. If you want push button operation, and a well made turntable, vintage is the way to go.
It might surprise some that this is very much a matter of common sense. The job of a turntable is to rotate the record at a constant speed, and support the stylus with the least possible amount of friction, while holding it as still as possible. The vibrations in a record groove are only a few microns wide. It should stand to reason that a flimsy lightweight plastic turntable, with sloppy poor quality arm bearings, and a platter that wobbles, would not be the best choice here. This doesn’t necessarily mean that the heaviest turntable is the best, but that is generally closer to the truth than not.
Phone Cartridges and “needles”
A phono cartridge is the little device on the end of a tonearm, and includes the stylus or “needle”. Movement of the stylus in the record groove generates a small electrical signal. Rated live is typically 500 to 1000 depending on manufacturer and model. We have seen much greater use without significant wear. The take home here is that skimping here is going to limit the sound of your vinyl system, no matter how big the amp, or how large the speakers. If you have an old turntable with a bad stylus, or have purchased a used one that needs replacing, make sure the cartridge or stylus has the brand name logo. Many resellers today are selling chinese counterfeit clone replacements. We recommend avoiding these completely.
Amplifiers and Receivers
Amplifiers (amps) take the tiny electrical signal from the turntable, and magnify it many times to move the magnetic coil in a speaker enough to make audible sound. Amplifiers may be in a single box, or may be split into two or more boxes. A one piece amplifier is also known as an “integrated amplifier” and when we separate it into two pieces, these are known as a “preamplifier” and “power amplifier“. Separates are usually more expensive, but offer greater performance due to the dedicated power supplies, among other reasons.
Like high end cameras, separating portions of the amplifier this way can yield better performance. A receiver is simply an amplifier with a tuner (radio) built in. Conversely, a tuner is just the radio portion that requires a separate amplifier to produce sound. In the mid 70’s, the bottom of the line name brand receiver was around $179. Today, that would be nearly $800.
How much power do I need?
This is often misunderstood. It’s also complicated by the fact that mainstream amplifiers sold today are rated differently today than in the 1960’s and `70’s, when methods were more regulated. A modern receiver claiming to be 100 watts per channel today would probably rate at 40 or 50 watts if the old methods were used. A mid century 50 watt per channel receiver is actually quite powerful, and a 100 watt per channel Pioneer receiver from that era is a monster. Many listeners with a small space would be fine with a 15 to 25 watt per channel vintage amp.
No, not the chant, it’s an electrical unit of resistance. Speakers are typically rated between 4 and 8 ohm. This is normally not something to worry about, at least with most vintage gear. Many modern amps and receivers only support 8 ohm speakers.
Amplifiers from the 1980s and earlier in original condition will need some amount of service. Most likely pretty extensive service, in order to be reliable. You can purchase equipment that has already been electronically “restored”, or find a good bargain in original condition that is still in working order. Beware, as that Craigslist or Ebay buy might seem a bargain at the time. It may be, not when you discover the cost to restore it to full operation is $200 to $300, and up to $1000 or more for larger and more complex pieces.
It cannot be overstated how important it is to choose a good a set of speakers. This does not necessarily mean the largest, highest power rating, or largest number of components either. It also does not necessarily mean the most expensive ones are the best choice. There are many good inexpensive modern speakers. The corner cutting in recent years of turntables and amplifiers was not applied to speakers in quite the same way. In fact, mass production and low cost overseas labor has benefitted the consumer in recent years.
Yes, there are many great vintage speakers. Make no mistake, the fact that they a speaker is “vintage” does not mean in any way that they are superior to modern offerings. Many speakers produced today, especially in the higher end of the range, represent the absolute state of the art. A great infographic on how speakers work is here.
Vintage Speaker Potential Issues
In the 1970’s, a foam material was introduced to connect the woofer (big bass speaker) to its metal frame. This became very popular, and is still used by current speakers. The foam is light, and very flexible, and offers some performance benefits. Unfortunately, it deteriorates after about ten years. In most speakers it can be replaced, kits are available for many speakers for DIY folks. In most cases, it’s wise to have an expert take care of this.
Many mid century speakers had level controls. Turns out, not such a great idea. The controls are almost always a source of problems on these speakers. A problem that can definitely be corrected. Some speakers use electronic components internally that degrade over time. These to can be replaced. The typical result is often a significant performance improvement.
Power Rating and Efficiency
One of the biggest misconceptions is that a 100 watt rated speaker could not possibly be damaged by a 50 watt per channel amplifier. Totally wrong, as an amplifier turned up until it distorts can easily damage any speaker. Speaker rating is simply a rough guideline. Ironically, efficiency is commonly overlooked, and easily as important if not more so. A more efficient speaker will produce a larger volume for a given amount of power. Important if you’re looking for the most volume for a given power. A more efficient speaker does not necessarily mean better quality sound.
What type of speaker is best?
There is a mind bendingly wide array of speakers produced over the past 50 years or so, large and small. In short, there is no one best speaker. It depends on your budget, preference, room size, amplifier, and so on. Typically, speakers have two or three “drivers”. Let’s get rid of a myth or two right away. Speakers with more components are not automatically better that those with less. High tech cutting edge components outperform speakers with more common drivers is yet another one. Some of the most listenable speakers ever made use the same technology as those made over half a century ago.
Two things are pretty safe bets when comparing a small monitor or bookshelf sized speaker, to a speaker with a large woofer, or a tower type with multiple smaller woofers. Well designed large speakers often produce fuller, deeper bass. Larger elements typically move more air. In most cases, large speakers can play safely at a higher volume, and/or fill a large space with full range sound much more effectively than small speakers. If you already have small speakers, and seek to extend the bass performance, a good option is to add a subwoofer. Small monitors and a good sub can produce the full audible spectrum. Make no mistake however, in terms of clearly reproducing detail, the human voice and most acoustic instruments, you’d be better off a pair of fine small speaker than a middling pair of large ones, or a cheap satellite subwoofer combo.
Building a System
For most of us, price is definitely an object. It’s a little confusing to decide on dividing your budget between a turntable, amp, and speakers. One popular school of thought is to spend most of it on speakers. We don’t agree, and instead suggest spending as much or more on the turntable. If you’re on a very tight budget, you can add an inexpensive phono preamp, and just listen through your computer, existing stereo, or powered speakers. You can later add a receiver and speakers to complete your system. You can of course connect tablets, phones, mp3 players, etc. to these vintage amps. As for playing vinyl, if the turntable is not delivering, no amount of power, or exotic speakers can overcome this.
The Bottom Line
The same is true of vintage gear, as it is of new audio equipment. You should listen to it yourself, with music you are familiar with. Especially with equipment that is over 40 years old, you want to know everything is working as it should. For this reason, we suggest caution when buying from Craigslist or Ebay. Ask if the equipment has been restored. In the case of amps, receivers, and some turntables, ask if it has been “recapped”. Many sellers sell units that need work, and neglect (intentionally?) to share this fact. If you do buy from these sources, we suggest making sure you can return it, or buying with the knowledge that you may have to invest in servicing your new purchase.
