Tube Amp Archive

As has been said - the differences are subtle and very situation dependent. Personally I love the smooth and rich sound of RCA NOS Black plate EL84s for small SE amps, however they are expensive in matched pairs and quads. For PP in a 15W or 30W class A amp - JJ, Sovtek, etc., does not matter too mu...

Certainly not one of their best efforts... I'd spend the extra $60 and upgrade the output transformer to a good USA made Bassman unit, especially if you are going to be pushing the amp, which I suspect you will be if your previous build was not "loud enough".

Just got a new 68 Vibrolux Reverb reissue and have been using that, so without the urgency of needing a mid sized amp this build is going very slow. But I have finally decided on the configuration. I'm using the existing Fender Hot Rod Deluxe iron good for about 35 watts and I'm adding three more tr...

Hi David - Not exactly sure what you mean by cloning half of a clone, but I am going with the 3rd gen OD.

I'm not aware of any such conversion on the forum to-date, but it seems straight-forward. I'd go for the D circuit if you are after a nice tube OD, maybe squeeze a D'lator buffered loop in if you can find the room. No reason not to try the transformers you have and see how they work out. Who knows?...

Hi There, I've been lurking here lately seeking some inspiration for a new build. Been building amps for 40 years but never focused on Dumble. Currently playing through a Fender (Rivera Era) Twin II which is too heavy and too loud. Not crazy about the OD in the twin but the clean sound is killer. My...
