My 18/9 Watts ODS

[Jmc12]

Here's my realisation, basically the #94, with 2x6V6. I added a reverb and an active FX loop. Triode mode to lower the power if needed. I had a Celestion G12T 75 that is working pretty good. I love the tone of that amp, nice clean, but with an incredible crunch when pushed, and a big fat overdrive channel.

That looks great.
Nice work.

[Colossal]

Really cool! Nice work!

[Reeltarded]

That looks great and fun and I love your speaker selection!

Nice build! That is a very cool looking active FX loop. I have never seen one with a miniature tube like that.
Who makes that?

Cheers
Guy

all the components, plus the active loop and the power supply are comin from Tube Town in Germany ( https://www.tube-town.net/ttstore/kits/ )
the mini tube is a 6112. this is very much inspired by the dumbleator.
The wood is acacia that I Bought at the local Brico....
I Designed my faceplates with Inkscape, And Tube Town engraved them.

Excellent!
(this works both in french and in english ... )

I've thought about that loop a few times but the PCB jack spacing is the wrong size for the standard ODS Dumble chassis!! which is a shame as it looks like a great little solution.

Hi there Jmc12,

How are you getting on with the FX loop? I'm thinking of implementing one of these in my build and I'm curious if you have any tips or mods regarding its circuit. Also, where did you take the B+ from? I drew up a little sketch of the circuit that incorporates the bypass and series/parallel options, included here.

Another build question maybe, looking at the schematic it seems the jacks need isolating to avoid a ground loop. Do you know what kind of jacks they use?

Cheers!

Hi Stephen,
I'm using the Tube Town 6112 FX Loop, which is about the same circuit than the Dumbleator. I take my B+ from B5, and there is a dropping resistor R11 to change depending of the B5 voltage.
By the way, I made a mod on my reverb Circuit. I used the classic Fender deluxe reverb schematics, and added the preamp just after the 3.3 M resistor.
For the jacks, they are plastic ones, so they are not grounded to the chassis.

That is a remarkably well done build!! Bravo!

Are you enjoying the tone? How is the idle floor noise? Is it quiet at idle?

With respect, 10thtx

[Jmc12]

Thx,
It's a very quiet amp, and you got a very acceptable floor noise when the OD stage is engaged.
I like the tone, when you push the volume in normal position, you got a very nice crunch, and the amp breaks out depending of the guitar volume position , à la Trainwreck....
I built another one for a friend, he wanted a head and a separate cabinet. he uses it like Robben Ford, no OD and pedals , and that way he is approaching the Robben tone.
