This is a TAScam PA-20 Mark II stereo power amplifier.  Listed as parts or repair because someone modified it adding a second level control that had no purpose.  This has been removed, but there is still a hole in the front panel.  I replaced the electrolytic caps accept the power supply ones which were good.  Other components checked, sine/square waves good and music test good.  Also the stereo/mono switch is not good.  It is working now in stereo but the contacts are not good.  I wouldn't recommend moving it.  Another reason for parts or repair.  The speaker output connectors work but won't accept very big wire.  The soft start and protect circuits work as does the level control.  Headphone jack works and disconnects the speaker outputs.  I was surprised how good this amp sounds both through the speakers and headphones.
