re: A75 Series 2

Upon switch On, I was getting some strange rustling noise through the speakers for 10 seconds or so.
I traced this to the Speaker selector control, due to the contacts aging over time. It’s a odd type of rotary switch, so no direct replacement seems available.
As I only use one set of speakers I just hard wired the selector control so the “A” speakers are now always on. Result! Great amp, wonderful quality.

Had this amp since new and its still sounds fantastic with Spendor BC1s and Logic tempo table. Had to have new output capacitors fitted for £50 by local repair guy but well worth it. Smooth powerful valvey sound.
