If buying vintage speakers, be sure to examine the woofer surrounds, and beware of cracks. Rebuilding these can cost hundreds, and the external crossover will usually need to be serviced as well.

In the case of the Bose 901, a total of 18 speaker drivers are used. This is actually true of many brands in the 1970's, and on into present day. The popular Bose speakers on the other hand, utilized woofers with a foam material that deteriorates over time. The crossovers use capacitors of a type that are very reliable, and may still test in spec decades later. A vintage set of Klipsch Heresy speakers for example have 'lifetime' woofer surrounds. Speakers on the other hand, can vary quite a bit. Restoration for this receiver is well over $1000. Much more for very large receivers like the Pioneer SX-1250. Otherwise, you should budget for service that will likely be into the several hundred dollar range. Ideally, it's best to buy a amp or receiver that has been restored or 'recapped'. Spontaneous noises, especially loud pops, can be signs that the amp is overdue for restoration. Often, a temporary remedy is to move the control or switch rapidly back and forth a number of times. Noise produced by moving controls is usually relatively minor, and can be remedied by cleaning with a product like Caig 'Deoxit'. If you are buying a forty year old amplifier or receiver, be sure to check it out completely. Regular use, especially for changers and fully automatic turntables, is key for long term reliability.ДЄmps and receivers on the other hand are another story. It is possible to have the idlers rebuilt. If left unused, these turntables usually require a significant amount of work. Some very early turntables, like Dual, Garrard, Rek-O-Kut and others use an idler drive system. It's usually best to have this installed by someone who is experienced. If a brand name replacement cannot be found, go with a new cartridge. A new stylus might be needed, but beware of off brand replacements. Something that can easily be changed by the owner. Often, an old belt drive turntable can be put back in operation with not much more than a new belt. Unrestored vintage direct drive turntables may need more extensive service than belt drive turntables. Many vintage tables are better than entry level modern offerings. вЂ‹ What to know about buying vintage вЂ‹ TurntablesДЄ good turntable is the most important choice for a vinyl system. After about 1980, higher end audio would continue to excel, but the typical affordable amplifier, turntable and receivers would continue to fall in quality for years to come. Not only was this equipment well built, but this equipment was designed to be serviceable. Brands like, Pioneer Sherwood, Sansui, Technics, Yamaha, Kenwood, and Sony were some of the leaders in this era. Especially in terms of build quality, sound quality, reliability, and serviceability. We believe that many of the amplifiers, receivers and turntables from the 1960вЂ™s and 1970вЂ™s are superior to their modern counterparts.
