So like this?

Re: the drain resistors - I think I understand that - basically gives the latent charge held in the capacitor at the point the circuit is switched somewhere to go?

Looking better already. Just for the anti pop 1M's on the collector.
Dont see the need for Switch1(a) at the input. You can feed signal to both inputs all the time.
Its the output you want to switch out. You could simplify the clipping diode switching too.
Cant see the need for switch s2(b)

If you remove the switch you will get more pickup loading.  The switch makes it work like two separate ckts.

Would that not mean that all diodes are always on as they're all effectively connected via the output?

Yep Is that not the same as yours ?

Mine is switched at the output 2b so the 2 diode clipping circuits are totally isolated.  I don't know if that's necessary but to me it looks like it is.

Looking good now.

Thanks Rob!
is it work? I have same issue with popping when switching transistor. Thankyou
