What is the P/T + O/T difference...between the JTM 50 and the JTM 45? I bought a Ceriatone JTM 45 off a guy over at the gear page and I was thinking about converting it to JTM 50 specs. Will I have to change out the trannies or can I use the JTM 45 trannies?

Thanks,

Ed

You should give Nik a call...
But from a quick glance...The OT can probably function with either EL34 or KT66 as far as the impedance that reflects back from the Speaker-OT-Tubes.
You will have to check the current draw difference between the 66's and the 34's. At a glance, everything else looks pretty much the same, but I have to get out of here.
Send your question to Nik...
Good Luck
