Knight 40-watt Stereo Tube Amplifier model KA-55 with original manual – $89 free ship AS-IS

Looks like a very nice stereo tube amp if you are willing to do the rebuilding/recapping necessary to make it sing to you!

Sansui 500 tube receiver

Sansui 500 Tube Receiver/Tuner — $279 free ship USA, AS-IS

Here is a quality Sansui model 500 tube receiver/tuner. Selling As-Is, exactly as found from previous owner. Cosmetically, it is very attractive in my opinion, with clean front panel.

I did some quick testing, and it has basic functionality — FM tuner receives stations, audio output is fair (bass is weak, power output is below spec), trannys are good, etc. Unit appears to be almost all original except that output coupling caps were replaced with orange drops sometime in the past. Otherwise, it looks original as far as I can see, and therefore needs recapped and other normal servicing to restore proper working condition and stronger output. Tubes are present and appear to be mostly original Japanese Matsushita that were supplied with the unit.  Output tubes are a quad of 6BM8 (two per channel).  If you want to take the effort to recap and service, this Sansui 500 will be a high quality audiophile tube receiver for you.
