That said they DO differ. There´s versions of it that lacks the voltage selector part for instance. There´s versions that use straight up 220VAC motors for the reverb unit..and so forth.
In other words don´t be surprised if your particular unit doesn´t conform to schematic down to the last part.
My own amp,as stated,is up and running and pulling its job off as an absolute champ. True enough i´ve modified mine rather extensively from an electronics point of view,but it´s all modifications that can be taken out...and thus the amp be put back to stock.
The ECF tube is mentioned. It is my findings,as a general whole,that using pentodes that sees overdriven sounds farther in a given circuit is a no-no. They simply do not take kindly to overdriven signal. In short...it´s sounds real bad as they do.
Ergo i played around with a different phaseinverter setup in my own,and the final choice was for an ECC-99 from JJ. Does the job well.
In turn. Like stated above i´m still having an argument with the reverb of it. Them toneheads in the picture are old Bogen UK-100 ones,and they seem impossible to nor find or replace.
As ALL of them were shot on my unit i to this day don´t even know the inductance of them. Nor the DC resistance even. They seem to have a reputation for going open circuit and as such i´m a bit surprised that noone seems to know the specs for them. Have written Bogen i Germany to no avail. No reply even...
So.
What i´m planning to do as of current is convert the unit to be a tapeecho instead.
I´ll stick to the drum still being the drive unit of it,just reroute the entire thing a bit and replace the heads with common taperecorder ones and thus at least get the unit up and running again.
Going to use a common capstan roller...springloaded of course,and take it from there. The "pillars" of the unit i´ll turn to size in my lathe (drehbank?) out of common POM plastic material.
