Maybe talk to Haberdasher about etching you one... or ask around, there's bound to be someone else who can do a board for you.
I may do a fabbed board at a later stage if there's enough interest

[BRGPollen]

I'd Be interested in a fabbed board!!!!

and the tube / tube socket has arrived ! ! !   
BTW i got a decent ribbon cable from mouser

[jeffaroo]

Im in the middle of building the Watter, C2 & C4 call for 27n all that Mammoth had was .022uf
will this work, or should i get the right ones from mouser?

Oh btw, im gonna get the MOD 8" for this bad-doggie !   

[nzCdog]

Woo!  You can use 22n or 33n, but it will sound slightly different... I tried lots of different values when designing it.  You could use 22n in parallel with 4n7 to get approximately 27n if you prefer...

hi

It´s possible to add bass and treble?

on the video that you post and after the rangemaster you are using a OD klone.

What was it?

Thx

[nzCdog]

Well feel free to experiement!  There is a bright/fat switch in the design which alters the frequency response, as well as some suggestions for Cap subsitutes in the build doc ...
The pedals in the video were a HBE Germania, and Madbean Sunking

Hi , Have enjoyed following this build and the end product looks and sounds great.

I was wondering if it would be possible to power this project with a RoadRage???

I just realised the RoadRage would not be able to deliver 200ma  duh!!!  Anyway it will still stay on the wish list

Thanks!

No... the tube heater draws too much current for the roadrage.  For this project you need a regulated 12VDC power supply capable of at least 250mA depending on the tube you use.

Learned about this through a post on DIYstompboxes...will definitely check it out!  THANKS!  Larry

Welcome to mad bean ! 
i think it was me that sent you here

...finnishing my lil watter up here... causing a bump on this thread:)

Foolproof question (statement?): There isnt any black magic going on, right? So: I dont need to connect pin 9 from the tube socket to the board.

***

Another thought, even though i think we play safe: As we are dealing with pretty much more power (and current; 1W in 4Ohms means 0.5A) here, than in "the average stompbox", did you calculate the correct pcb trace width concerning this?

***

Well... ill be back pretty soon with the finnished build:)

Cheers

*** EDIT: Hmm, my intention was to write this post in the "member projects... Lil Watter thread", and i guess i was doublereading while posting... Well, here it is anyway

[selfdestroyer]

If anyone is interested I'll put together a project sheet with the schematic and pcb artwork at some stage. 

Um, heck yes? This is something I've been thinking of for a while (combining the tube pre with the 386).

You got two excellent sounds for such a simple amp in that video: The rangemaster (LM386 amps tend to sound dark) and the Les Paul + reverb with the amp dimed. I don't think it handled the Klon as well, though.

Agreed.. I would love to see this also.
