Re: Hmv 2126
Got this sorted now. Audio output device problems fixed by brute force replacement of two AC154s and an AC169 bias compensator with a pair of BD136s and a couple of bias resistors. Not particularly elegant but decidedly bombproof compared to the original! I tried just siliconizing the original circuit but gave up and settled for simple.
It's probably on borrowed time- the AF117s in the IF were already screen snipped when it arrived, but that can be S.E.P. (HHGTTG ref there....)
