Are they actually dead or something?

I guess they are Germanium and in that case leakage is *normal* .

What are you exactly trying to fix?

Found the REAL problem, ( after repairing power supply) Q12 is MISSING in the splitter of driver section, Looking at the reverb section ( same part #`s) Q12 is 2SC253383...would you have a cross reference on this? Man, i`d really appreciate it!

Hi Groov, welcome to the place.  It is good form to at least link a schematic when discussing something, especially an uncommon amp like this one.  I Have no idea where Q12 might be.

Just looking at your part number, I have to assume the part is a 2SC2533.  The 83 is probably part of a date code or something.  But I could be wrong.

Have to agree with Enzo,

Here are the stats on the 2533, the page has an equivalent search on it

Without a schematic, I haven't any idea what to tell you.  You apparently have the schematic, so can you post or link it?
