Got an EC Tremolux on the bench at the moment and thought I'd trace out the schematic


Here you go.

Would you mind posting that in a pc friendly format? Maybe pdf, or png, or sch?

Thanks Pete, I was wondering what was under the hood in those EC amps.

Please let us know how it sounds, really how the trem sounds.

Is there an RC missing on the LFO in your drawing? Looks like only 2 RC phase stages from LFO plate to grid?

The amp has fairly earlyish breakup - like a 5E3, and the trem sounds really good. The LFO C/R network is 0.033uF/3MRA-0.01uF/1M-0.01uF/1M

Thanks Pete.

I'm amazed they want as much cash for these things as they do.  Seems kind of ludicrous
Thanks for the scheme!

FYI - 'Dave H' over at ampage did a sim of the bias supply if one of the .1uF coupling diodes is increased to .2uF. (attached) (I.e. you should be able to get -50V out of it)

Any ideas for the unused triode?

I just now noticed the year was 2019.  I thought it was a current post.  Here's an idea, nonetheless.
