That's very generous of you guys. Thank you.

I will check them out. Thank you.

Might anyone know where to get the Matchless "Turquoise Shower Curtain" amp covering? I've scoured the internet but had no luck finding an exact match.

For you guys who’ve built the NOTADÜMBLË, what do you think of it? When I put it in front of the Dumble style amps I’ve built I wasn’t all that thrilled. In front of my tweed deluxe it freakin’ rocks though (especially the clean side).

Me too! It comes with goop to put over the circuit.

R.G. Can you recommend a software package that uses SPICE and a graphical user interface?

I have yet to see a real ODS with F&T caps in it, yet we keep seeing folks put them in their amps and expect them to sound like the real thing.... :shock: One of the most famous ODS's of all time has F&T's in it. I know we talked about this recently but I figured I would get others opinions on it a...

What does "grainy" sound like and what might cause this? Alan I’m not trying to be a smartass or start anything….I would like to know. Harsh, irritating especially in the high end, definition and clarity lacks up top and doesn't sing , high end harmonic feedback also subsequently sounds terrible an...

I don’t know how related this is but there’s a guy on GitHub who created software and a gui to interface with the Tonex One. You can use all twenty presets and have access to all settings. I use it and it rocks.

Good point B Ingram. https://300guitars.com/articles/rectifi ... rop-chart/

You might want to check out a 5V4 also.

I may do that. The 5U4GB is a spare I had.

No load 5.64 Vac
5AR4 5.37 Vac
5U4GB 5.27 Vac

Looks I’m ok at around 6%.

I would pull the rectifier tube out and measure no-load voltage on the 5VAC winding, then plug in a 5AR4 and measure 2A load, then repeat with a 5U4GB. If the voltages drop is ca. 7-8% from the no-load voltage with the 5U4GB, I think it will be ok. Makes sense Martin. I'll do the tests later today....

Hi Fender People,

I have a '67 deluxe reverb and the B+ is around 450vdc. I'd like to bring that down a bit so I am considering swapping the GZ34 rectifier for a 5U4GB. Does anyone know if the power transformer (part 025130) can provide the 3A of heater current needed for the 5U4GB?

TIA

Alan
