Hi. I do have parts for sale such as MRS25 1% resistors by Vishay/Philips,Dale ,el.capacitors,PP capacitors,Mica capacitors, output transformers for tube amplifiers made by UTC,Stancor,Peerless,Acrosound,Chicago transformer Co. . Passive components are NOS . Some of transformers NOS too. NOS semiconductors -zener, rectifier diodes , TL431 IC . List would be too long so,Please,send your request and we can discuss details. Thank you for your interest.
I have Acrosound TO-330 , Dynaco A-430, Stancor A-8052,A-8053. Also UTC LS-58 which is listed at 40W but with 20-20 Khz within +/- 1 DB so you can safely consider it good for 50 w . Also I have complete Bogen MO-100 which is 100 w and which mod was described by D. Gillespie if I remember correctly at Audiokarma . I wouyld also recommend Peerless S-240 which is also 40 W but again with 20-20Khz bandwith.
Also I have Bogen MO-120 ,Grommes -S-100, Bogen MO-60, Grommes -S-60 which are 100 and 60 W amps. McGohan 100w , Heathkit W-7 [55 W ] , Dynaco MKII and MKIII [ 60 W ] . Are you building from scratch or modifying something?
I did try to list general parts I have - complete list could be hundreds of items - resistors different values [ AB, Dale, Vishay/Phillips ] , Capacitors different values [ PP, Mica, Siemens Poly , Evox , electrolytic cap] , Output transformers , input transformers . I collected parts for my projects for many years ,same with tube amps.
