Re: Tube basing Question

The 9A is very similar with the difference being the grid and cathode are reversed for each triode section. You might want to check this again as the 9A family is much more common (12AX7 etc) in guitar amps.

If it really is a 9CZ or 9J, the attached link to download a very nice FREE tool from Duncan will answer all of your questions.
