seti Posted August 23, 2021 Share Posted August 23, 2021 This is in two chassis. It has many variacs or are some of them variable resistors? The two tubes in power supply are OA3 and the second chassis has 4 6l6gc 4 12ax7a and two 6sc7 tubes. Very good DIY but the parts are scary old. The output transformers are very small... This is power supply chassis Quote Link to comment Share on other sites More sharing options...

babadono Posted August 24, 2021 Share Posted August 24, 2021 @setithose look like rheostats i.e. high power potentiometers. Was this Mr. Medwin's yard sale? 1 Quote Link to comment Share on other sites More sharing options...
