Quad 303 supressor values?

[6V6dude]

Anyone knows the values for the switch Rifa pop suppressor? It doesn't say any on it and it's blown. Well, it's been blown for years and I get no pops but I've came across a bunch of suppressors so maybe one will be the right value to put it back in the Quad to keep it neat.

330n or 220n is fine. Your suppressors should have suitable values, no? I googled 303 schematic, looks like 0.03uF (not clear on this image but you can google better image). 0.03uF = 30nF. To me it's too small to be effective, but you have noticed that there was no problem without it. So choose any one that you have, around 100n or less.

C4 is 0.03uF. No need for any larger and was fitted to serial number 11500 and above only. It suppresses the mains borne RF, if any. It does not stop a power off pop. As there is no power switch, there is no need for one.
