Very cool, I have to give it to you as you take your clones to the 9's. It's good to see other Dumble topologies lately, something other than the ODS.

I finally found me a relatively clean, cheap and working donar Fender (Super Reverb) chassis for my next Dumble build, one of the UP versions.

I always liked the idea of this amp but lost interest after talking to one former owner. Still I always loved the construction and still can't grok how this sort of amp, set-up and running properly, would not kick ass.
Look forward to seeing and hopefully hearing this one m8.

I don't want to be like some who keep secrets here, but I want to build the amp first (and be the first one here to do so) then I'll show and tell all. I hope this turns out to be a good amp for people interested in an easy-to-build Dumble circuit. It does not have all the complexity of 100w and the switching and the pre-amp switches of most other Dumble circuits. That will make it easier to build. I hope the architecture I'm working on for that main board will live on in many interesting tonal interpretations once I post the final version and schematic.

Very cool, I'm anxious to see the final result.

Hopefully this build doesn't take quite as long as your HRM did.

I keep an old iMac up and running because, frequently the older software is easier to use and runs faster. Plus I have a lot of old software. I like Macintosh, but I'm disappointed that my new 27" iMac can run Windoze but not 68k Macintosh software!

I ordered the raw materials for the chassis and PC boards yesterday. Tube sockets and filter capacitors are on the way also.

I'm very interested in both the Manzamp and the UP TM is building nice projects guys.

Did I miss something?? The Ultra Phonix has been de-coded?? I check in most days, maybe it's time to stop sniffing glue........

Chassis arrived today.

It is pretty thick because it has no end plates. I'll probably take it to a local machine shop to cut the holes, unless it is stupid-expensive. In which case I'll just spend the money on some metal hole cutting bits.
