Re: If I want to build a Dumble amp : which one ?

What I read here is disappointing and offensing. Of course, you can read, understand, believe or suppose what you want. Just try to search the web if you find some on my reputedly "commercial products" on sale : good luck. There's none, and that's a fact. Amps or stompboxes building business is not ...

Re: If I want to build a Dumble amp : which one ?

I didn't think ANYONE would modify an image of one of jelle's amps and post it.. OK. I think you don't understand what was the purpose of that image modification, despite I explained it. I suspect you don't know me very well at all, but rest assured that I have as good an idea as any. One thing you...

Re: coupling cap question

Would a leaky cap cause 120 cycle hum? It can, but along with other symptoms like distortion, motorboating or parasitic oscillations, fooling bias of the tube after that cap, high and unstable idle current, glowing plates or screens... How high does grid voltage have to be to indicate a bad cap? As...

Re: Bias Problem

My PT's bias tap puts out 47 VAC. That's a correct value, found on most Fenders, Boogies and Marshalls. A layout doesn't speaks too much to me, I prefer a schematic, sorry... But I am not Phil_S ! Like him, I would supsect a problem not necessarily due to the bias circuit. 0 - Did your amp worked f...

Re: If I want to build a Dumble amp : which one ?

We can only imagine how Dumble might feel...
Do you know what he tooks from Mr. Leo Fender, like Randall Smith, Ken Bran and many others - including us ?

I think that a WELAGEN ODS with integrated digital reverb option might sell...

Re: SUPERTWIN (RM): converting from SS to a AC3 Twin Top Boost

Fine job, LuciMan ! Your SuperTwin looks like to be the GrandBrother of my AC3 Top Boost :wink: Thank you very much - your Escort-modification looks nice too. :) How did you manage to realize the input stage & a top boost circuit with just one ECC83? Cheers Claus Thanks Claus, I called my amp AC3 T...

Re: Effect Pedal building

Hello All, There are nice releases here also ! The HCTO. Despite its name, this has nothing to do with the circuit of the commercial Hiwatt Custom Tube Overdrive. One single 12AX7WA on high plate voltage. works with an external 12VAC 1A ext. adaptor. You go from light overdrive-boost to Pete Townshe...

Hi, I have seen that pic before. :wink: http://www.welagen.com/product/80s-overdrive-special/ Jelle Yes, of course : this is the picture that I modified to see if the additional pot would enter the frontface and give a satisfactory look, along with a logo design test.

Re: How to Lacquer Tweed??

I would have lacquered the tweed of my small Gretsch G5222-VCM, but unfortunately, the adequate products are difficult to find here in France. De guerre lasse, I finally just applied one coat of clear satin polyurethane finish (Vernis Satiné Polyuréthane Longue Durée SYNTILOR !) and find that the re...

Hello Aaron, bluesfendermanblues kindly pointed me today on your Sonorous Sublime topic : Fine Marcus, My goal is to integrate an Holy Grail Nano inside the amp itself (like on some of my other amps : Orient-Express, Val-King), and the HGN is guitar level, so an adaptation of the loop level is proba...

Re: If I want to build a Dumble amp : which one ?

Abslolutely fine bluesfendermanblues ! At the first sight, Aflynt seems to have built something very close to what I am planning to do. Before finding your reply, I was designing an extrapolated project frontview of the Overdrive Special Reverb by Guilhem : [img:1400:699]http://img11.hostingpics.net...
