Do it Mike!  ;D

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.

Hey Bengt  :) No black magic, I promise.  It's a completely meaningless solder pad just added for completeness.  Ignore it if you wish

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?
Good question... the pcb traces are plenty big enough for the currents flowing in this circuit... fyi here's a handy calculator

Well... ill be back pretty soon with the finnished build:)
Awesome, can't wait to see the build pics! 8)

Done, ignored:)

Ah great, you looked over it allready.

...youll find it all - including soundclip n stuff - under the "june contest" board:) Edit: Link: http://www.madbeanpedals.com/forum/index.php?topic=10415.0

... and to come back to our earlier discussion; i use the N-4 version of the LM386, and it works just fine. I think you can update your build doc with that recommendation (if not allready done? I havent followed all development about this watter the last months).

Cheers mate! Thanx for a great circuit!

Looks great Bengt, nice build!
I'm glad you like the amp, I've uploaded a new project doc mentioning the N-4 etc in the project thread
*edit whoops wrong link*

Normally i'd be nervous of doing amp work, but something that small seems pretty safe to try out. I'd be up for one if someone fabbed some boards!

Love it!! do you have the pcb layout? I have a spare 1 x 12 cab...sounds like something I might have a use for.

P.S. I clicked the "doNOTclick" , yeah sucked me in for about an hour. Being a dog owner I think I might have experienced most of those instances,lol

Layout can be easily found in the Members Projects section, if you don't etch, Haderbasher can make it for you ;)

This is seriously an awesome project, kicks the shit out of a noisy cricket!

Yeah the Noisy Cricket seemed lame by all the videos I watched. Maybe i'll etch myself a board.

Sir corey,

Just wanted to ask do you think this would work with a MJ2955 transistor amplifier right after the output.    with 2 mj2955's power can be raised to 30watts.   But i know mj's work as playback amplifiers.   what cha think.    I really love mine use it alot.    But jamming throught a home stereo the amp just can keep up with the output.

hi,i have a question,on the  schematic, R1,R2,R12,R13 is 3k3,and at your pcb layout, it change to 1m,why?

Not 3k3.... 3M3! You can follow either schematic, but not a mixture of both.  :)

I see where the confusion is now, a mistake on the build doc which I will fix and re-upload.  They are simply voltage dividing resistors.  Please see this link for the latest doc.  Thanks, and sorry for the confusion :)
