Missing k***s on my Peavey Amp.

Question

Hi

I have a Peavey xrd 680 s PLUS, which I know is a discontinued model. Over the years it has lost a lot of it's k***s. I don't want to replace it because of this as it works brilliantly. Can you tell me if there is anywhere I can get spare k***s? I have tried all the obvious places I can think of!

Thanks.

Louisa
