About two years ago I built a Dumble ODS #124. At the time I finished the build I didn't have much time to tweak it, build a head cab for it and get a speaker cab for the amp.

Over the last two years I managed to build a head cab (two summers ago) and this summer I built a 112 cab for the amp. The last week I have had time to tolex the speaker cab with my winter break starting. Over the past few months I also got to look back on the amp, fix a few errors and tweak it a bit.

The build is fairly standard. Minus a few things...
- 50W output section
- 3 way bright switch, polystyrene caps. 110pF-off-50pF
- Correct polarity on presence cap
- Audio taper on both Level and Ratio controls
- Glaswreck's PAB mod, 470K+33nF in series with 22M PAB resistor
- 5.6K MF NFB resistor, using 8R load
- 350K OD trimmer set 96.9K from wiper to ground

Voltages spot on, 437V on 6L6GC's plates. 286V/294V on the PI. 190V on clean and 200V on OD.

Running Winged =C='s in the output section now, biased around 48mA. Liked these over the TAD, Ruby and NOS JAN 6L6GC's I tried. Gotta play with the bias a bit and find the sweet spot.

- V1 is an old RCA 12AX7
- V2 is a Mullard reissue
- V3 is a 7025 pull from an old BF Twin
Gotta swap some tubes a bit more and really dial in the tone and get her singing. Should be fun, looking forward to this!

The speaker cab is a 112 ported back cabinet. Built from baltic birch with box joints. Running a 12" Eminence Delta Pro in it.

As for the tone, so far so good! #124 is defiantly a great amp for strats (all I really play). Very sweet tones and nice and balanced too. Beautiful rich clean tone. And the OD just rips, super smooth yet just enough bite. I really think the slightly attenuated high end of the Delta Pro helps this setup.

Anyways here's some pictures...

They sound good for bright caps. Bit smoother and peaky then ceramic or silver mica.

Stellar build quality (I think?).

I look forward to seeing more.
