Got it done. The 10dB gain boost is gone and everything works. Oh, and it sounds amazing. I'd be curious if different tubes would make any meaningful difference with this circuit. Has some one did any sort of testing in regards to tube selection? It already is quiet and smooth sounding. The question is for science.

Thanks!

Hey everyone,

I’m going to be building this eq once I receive the parts. I’m considering using the Edcor XS1100 transformers instead of the Lundahl 5402. I know this works, however, I’m not sure there’s enough space on the PCB layout.

Has anyone used Edcors with success? If so, did it fit without mods? Sound/opinions?

Greetings,

I just ordered the Don-Audio power transformer for this project. It's the model designed for 2-4 channels. The secondaries are: 220v, 9v, & 5v.  From the schematic it says to heat the tubes with 12v. I was told I need to replace some resistors and do some traces for this to work. Does anyone using this power transformer have any advice or input?!?!

I want to make sure I don't make any mistakes. I appreciate any help. Thanks!

Does anyone have a list or layout as to where the resistors go on switch it PCB?

It's in the document PQD2switches.pdf that is part of the build documents.

Thanks!
