i'd go with staining too...but a nice blue/green..and put those metal corner protectors on there....nice build..

That's my own 5W class A amp with two 10" Celestions inside.

Who needs tweed when you've got corduroy? 

Looks great!

[Ben N]

That does look nice, but isn't your significant other pissed about the couch?

Two 10s for 5 watts? Interesting.

I've got a champ with two 8" speakers.  Like it a lot.

found a WWII navy battle lantern in my stepdad's garage...promptly turned it into a ruby. kept the scratched, crappy paintjob and the original toggle switch. added a 5in speaker where the light was and added a toggle switch on the side to switch between the speaker and the output. i was really surprised this actually turned out. it started as a joke and came together in just a few hrs. the speaker fits perfectly too.

You're Ruby Lantern looks really cool

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...

Now that's imposing!

[Greenmachine]

Geez man.  Like a pro.

[birt]

that looks very very good!

[richon]

just finished this experiment...

12ax7 preamp (with classic blackface vibroverb fender EQ) with a 25K mid pot  (wicked)
12at7 as PI
5881 Tung Sol (x2)  with 455 as plate voltages
and all Classic Tone transformers...

sounds awesome!!!

[tasos]

Really nice!
No guts no glorry!

Well now i am stunned

ThunderBird based on AX84.com design

Started out as just a speaker cab build (don't they all) a little christmas project... I was so pleased with the result
I thought I might just use up the spare materials to turn one of my old combo amps into a head unit. then I thought
nah just build a new valve amp yaself.... Here it is..... only problem is that I still have stuff leftover from the builds
Now let me think....... oh no here we go again.........

Is that a complete custom design for the internals?

[tasos]

Stunning!
Diy can get so addicting!

The circuit is by AX84.com High Octane. I wired the circuit from the schematic not the layout diagram, which would have been too big for the box. it looks a bit messy
because the amp uses a universal hammond 369ex for a 230V supply and leaves un-used cables which I could not bring myself to cut, just in case.. I would have liked a
longer tag board to space the components out a bit. The only changes from the AX84 circuit is on the lighting, instead of using a filament lamp I have used cheaper Led's the
supply for which is taken from the 6.3V output to the valves and wired onto the end of the line using half wave rectification and a current limiting resistor and while i was at
it I fitted a red high bright led to shine into the head to give it a nice glow when on. These are my mods and have not been tested for safety
