I'd like to try out some 6ca7 power tubes on my new-to-me Hey What 504,,,, is it okay to use 6ca7 tubes in this amp without any mods? and what would the "ideal" bias setting be?

thank you!

Hi,anybody try a Fender style .1uf .047uf 250pf tone stack in a trainwreck style amp?
I use my C-Wreck primarily clean and would like to get a more fendery mid scoop/eq.
Before anyone says 'just buy a fender' I would like to work with what I have!
I'd also like opinions on fendery speakers such as Jensen c12n's with Vox style EL84 amps.

It's a difficult matter to understand.

Now, I understand that taking the pots out of the amp equals in having some resistors inside the amp instead of them. But, even if it must be psychological, i would be delighted to have an amp with no pots.

You should be pleased, no really, you have made them resort to underhand tactics and they will fail. BUT if you do change your parts to lower 'quality' cheaper versions and it gets out, then you will suffer. At the moment we all know these comments are unfounded and will defend you when we see them, please don't change your build philosophy.  Washington DC Escorts

I swapped the 150k to 180k and it is an improvement, thank you. I also changed the resistor on the PAB relay from 10M to 6M6. (Mine was 10m not 22m) This also made a difference.
In an earlier reply someone mentioned changing the bias bypass cap(s?) from 5uf to 2.5uf. Just wondering which one? There appears to be four of them.
Thank you for this.
