Re: express external bias-pot option question?

Has instructions been posted anywhere? i cant seem to find any. Thanks That would be the way to go. In the existing "express" BOM files found here it, indeed, calls for two trimmers in the external biasing options' list of parts. I'm going to assume that's for each tube? I've still yet to see exactl...

Re: Blackface Fender Showman....Sucks with Pedals

It just does not sound good, apparently after a bit of research this seems to be a common complaint. Thinking about it, the amp is probably too scooped. Most of the pedals i use are tube screamer derivatives, and you know the mid-range on those. The pedal that works the best is one of those dumble p...

Blackface Fender Showman....Sucks with Pedals

I have had this Blackface Showman for a while and was hopping the amp would be a good platform for pedals but it is not. The clean sounds awesome but hook up a dirt pedal to it and it blows. I have tried 3 to 4 different cabinets and about 20 different pedals and no luck! I would like to know if the...

Re: figuring out pt voltages.... a safe smart way?

The HV CT is the yellow and red wire (bottom first from right) and the other yellow (bottom second from right) is the HV Bias. The filaments have a CT its the yellow green (Top first from left). Sorry for the misunderstanding but the 120 is the primary, I forget that we have a bunch of non-American ...

Re: figuring out pt voltages.... a safe smart way?

Thanks that video made things alot easier. Ok so this is what I got the red wires are hv and are 375v measured at center tap. Greens are filaments and those measure at a high 6.9 or 3.45 at the center taps. Black wires are your 120. I am assuming the yellow wire (bottom second from right) is the bia...

figuring out pt voltages.... a safe smart way?

Hello. After a year or so I have started to build again. I didn't realize how Manny projects I had open..... from a completed amp that needed feet installed to half completed turret boards. One of the projects I have open is determining the voltages on a couple old transformers I have laying around....

Re: Single ended amp Filtering and Tremelo Questions

Ha! Yes did not even see that. I was confused as it was a circuit board and the other 2 20uf caps were on the other side of board, I really hate following traces. Now all i need is to use the jj can cap and run wire to the circuit board. That was very silly of me. To get the 40uf they ran to 20uf in...

Single ended amp Filtering and Tremelo Questions

Hello. I have to questions and thanks in advance. I purchased an old single ended amp (EL84) on eBay and it worked fine aside from the tremolo circuit and it needing a re-cap job.....volume fluctuations, excess noise, etc. Question 1: The recap job calls for 3 20uf cap in a single can but I was unab...

Re: Plugging unused holes in a chassis

Will check lowes, I also have a plumbing store right around the corner so I will try there as well. Doesn't $5 a plug at weber seem really expensive.
