Hi Grannyring,
Are we talking about Tube Audio Design TAD-60? If so, do you remember how many coupling caps and their value?
I have its schematic here, I see two .47mfd 400V from 12AU7s 12AU7s ? (I see one .1mfd 400V but not sure)
BTW: I took your advise on jb JFX caps on my Carver 180 - great result and way cheaper in compare with other brand
Thanks
