Solid State rectifier for 5E3 build

Post by Slim66 »

Folks,

I built the Tweedle Dee circuit with a Pacific Audio Deluxe Reverb PT and a Pacific Audio Brownface Deluxe OT. I would like to use a solid state rectifier in order to have enough current to add a 1 tube reverb. ( and maybe run 5881's).
Is there a problem using the Yellow Jacket YJR solid state rectifier in this scheme?

Thanks,

Slim

Running SS rectifiers will raise up your B+ by 25 volts or so , but the ultimate amount of ma your amp has work on is determined by the ma rating of your power transformer, not weather your running a tube or SS rectifier.

As long as your power supply filters can handle the extra B+ then circuit wise the amp will live fine.

The higher level of B+ voltage might give you another 2 watts of peak output wattage if your output transformer is not saturated already with level of B+ the tube rectifier is providing to the amp.

Also I would not run 5881s unless you have them sitting around already, I would instead get a set of JJ electronics 6V6 tubes as there plate structure is extra beefy and overkill for a 6V6 .

Yes, check the PT specifications. But you should be fine with a tube rectifier. 6 preamp tubes in a Deluxe Reverb. Only 3 preamp tubes in your proposed design. The B+ must be sky high in your Tweedle Dee!

The best excuse I can think of for switching to a solid state rectifier would be heat reduction. Five years ago I got a yellow jacket rectifier for heat reasons. The Yellow Jacket did not fit in my tube socket. Surely the manufacturer has fixed the pin size by now. But I would still recommend immediately testing the fit of a new one. I replaced my Yellow Jacket with the Sovtek version and it is working well.

But my preference for your situation is a 5R4GYB to drop the B+ to around 420 volts. It only uses 2 amps of heater current. New Old Stock is still available for reasonable prices.
