Hi chaps
the good news is that my rebuild of the BS ht-60 is virtually finished. Everything is working.
the only remaining issue is a (too) loud pop on channel switching. There is a mute circuit, which I am guessing is there to stop this from happening. Am I right?
I attach two extracts from the schematic showing the path of the mute circuit. Is there anything that would cause the pop if it has failed? There’s a J175 FET (18) a switching diode (half a BAV99) and a 100n 50v capacitor. The diode and the cap are tiny SMDs, which I find it hard to trust!
any help or alternative theories for loud pop on channel change will be very welcome.
cheers
