Great project.I will start to make one .I have a spare 12ax tube.Does anyone have the parts listed?

Why not a 12AU7? It should work much better at 12V than the 12AX7.

indeed i need a 12au7 but by mistake i bought the ax so i look for a tube circuit for this tube.

Dirk, I was wondering if you are selling PCBs for this project because, after building Bajaman's Real Tube Overdrive, I would like to build one of these for myself, but at the moment, I don't have any etchant to etch myself a PCB, I've got plenty of PCB material though, otherwise I'd etch myself a board, any help would be much appreciated....

You should be able to use any tube in this project, provided that it is pin-for-pin compatible, 12AU7, 12AT7, and 12AX7 should all work fine, you'll just get different levels of tube gain....

Hello
in the schematic there are two LEDs, which fulfills the function that is mounted on the pcb of the valve?, here I do not see

+1

if you are selling the pcb for a reasonable price i'm up for one...
I still cant etch myself boards...

It's mounted in the base of the tube socket.

No probe etching a few but I'd be more happy if I could do 5 or more at the same time.
Would 25 euro's including drilling, cutting to suze and fluxing the thing be OK?

preps better followup throuhh PM.

Yeah, 25 Euros sounds fine to me, I'd have to convert that to Australian Dollars though, do you accept payments via Paypal Dirk?....

Hmmmm...maybe a few other members would be interested in getting some PCBs for this project....

I might like a board as well.. Could you upload some audio clips, so i can decide if i like the sound of it or not?

I like the awesome look of the guts alot though!

Is this it: ?
If so, I'd like to have one as well

I reckon it is, since the way all the controls, the led, and footswitch are laid out, looks similar to how Dirk has laid things out....

Quite a nice sounding pedal, good Blues tone....

Ntot sure.
The layout is right.. but mirrored.

And the DC jack is relocated....

Or, it could even be that the video is flipped horizontally...

sorry the power is 12 dc or Ac?i have seen many schematics which say 12 ac.if here we have dc where is the difference?

Dirk_Hendrik · Post by **Dirk_Hendrik** » 24 Nov 2011, 06:59

DC please.

I just found myself a couple of JRC4558S ICs which I could use to build a vero layout version of this project, the JRC4558S is the Single Inline version of the JRC4558, I believe...
