Better Vintage Stereo Receivers
Do your homework and if you pick from Marantz, Pioneer SX, Sansui, Harman Kardon, Kenwood KR, Rotel RA, Sherwood, Sony STR, Toshiba SA, Yamaha CR and many others of 70 and 80’s vintage most likely you not go wrong.
So if the unit is somewhat working that is a good sign because it may not require major expenses.
Much emphasis primarily through the internet and YouTube suggests that in order to have good quality sound from your vintage receiver you must replace “all” capacitor not true. “If it is not broke do not fix it”.
Most repairs may require a replace electrolitic capacitors in power supply, some lamps and cleaning/DeoxIT and lubing the controls and switches.
It definitely depends on the unit condition. Some receivers were stored for many years and may need less work.
Others were running constantly in a closed environment which makes many capacitors go bad capacitors do not like heat.
