Pardon me, but @Robert : Do you have any advice for me? After inserting a 10R resistor between pin 2 and chassis on the 405 din socket, the hum on the right channel is gone, but still remains in the left.

Hi all So I inserted a 10R resistor between pin 2 and chassis on the 405 din input socket. The hum has gone away, mostly, in the right channel, however the left is still there. I noticed that the leads to the left channel amp (from the din connector) also have the shield going to chassis. Should...

So I tried replacing C5 and the hum is still there. @Ampex185 can you clarify what you did to resolve it? I don't understand what you mean when you said "do not carry the shield through on the case of the cable DIN plug at the 405".

Oh wow. Ok. So in your opinion, no need to cut "pin 2 to chassis link" on the Din input?

Hi. Also late to the party... But I'm having this same issue with a quad 34/405 (slight hum, even when nothing is connected to the 34, and not effected by 34's volume knob). I opened up the 405 and did notice the link between pin 2 of the Din connector and chassis. But @Ampex185, could you...
