Have to agree with Enzo,

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

THANK YOU GUYS  A MILLION! Do you know the PNP sister PART NUMBER to the 2SC2533? Thanks in advance!

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!

Need to replace the output transistors ( 5 ) in a Baldwin C2 guitar amp, ( leakage on edge on ALL.., low gain on 2 ofem) the PN is 466 then TRPV  6849

ANyone have  across reference?

Thanks in advance!
