Here is an amplifier I have been "servicing". I have LM4562 on the input board, replacing 5532, Panasonic/Vishay BC/Nippon Chemicon recaps (BC's to do + resolder that wire I broke
)
Ceramics to NP0/C0G x 6
It seems quite an uncomplicated affair for an amplifier and in part I think this might be partly why it sounds so good.
Look forwards to switching it on and testing on a speaker I do not mind being destroyed in case !
My friend recommended the amplifier 250RMS per side and it sounded quite good despite it's 14 years age. Bit of evening fun for me.
