i think OK1 has to be mirrored, isnt the Collector Emitter path placed in the wrong direction?

nice! but the resolution is too bad to name the IC's but the white ones looks familiar to me ....

just saw the PGS demo on youtube. great sound! i cant wait to see some guts!

made my first layout with eagle. i hope its not too crappy. i will etch it in the next days.

i would say:pre amp stage like NT-15, phase splitter and a fitted 12AU7 push pull output stage.

hi there, i spend a little bit of time for this weird stompbox. I dont know, if R6 is in the right position, this is the resistor from pin 1 to pin 3 on the fuzz pot. Also i dont get it out of the pictures, which cap is 10 uF and which is the other on,but a little swap would give the answer :). Can ...

the POG stompboxes are awwwwwwwwwesome. but i think theres no way to clone the POG 1 / 2. but i hope there will be more POG 1 in ebay, too until this will happen, i will finish my mxr blue box ...

thanks for the help. i was thinking about the "connect the transformer in reverse as usual" but i thought, there would be a easier way, like the power boost from one of the submini amps like the murder one. but i'll try it with a little print transformer.

which other options do i have for a good working high voltage supply???

hey there,

can someone help me with the high voltage supply. In the schematic there is a transformer, but i cant find one which would match (1:14 or something like this ).

Also i was thinking about a voltage supply like the Nixie Supply. Would it be a solution that will work well?

hehe, good look for creating this in DIY

Hi, my grandma gave me an old e-bass from my uncle, but the neck is cracked, so i think i dont get this instrument in one part away. It looks for me like an old 70's bass, maybe the single coil pickups are rare, i dont know, i cant test them, because of his horroble condition. I have made some photo...

thanks jim, i will test it when i have some XOR's at home and a little bit more time than now

another noob question, this pedal is really nice but can i mod it with a few steps from a octave below to a octave above? i think this would be sound great, too ..

for a boost power supply it's pretty the same inductor i have used and it works very well .

hi, thanks for your help! the sound is more whining, but in some switch positions also humming. the frequency changes when i get contact to some capacitors, especially the capasitors on the high and low end switches, also when i have the tubes unshielded. The Nano head is built in a 8 inch speaker c...

HI, i finished my ecc81 /12at7 nano head and it works with a huge problem. there is always a noise like in the fuzz factory, the frequency of this noise is changing with switching of the treble, bass and brightness switches or turning the gain pot. so i measured the alternate voltage first ... 80 mV...

the output transformer is a simple hammond 125 A, if you google, youre getting enough sites to buy one of them. I bought one for me for 20 euros.

the problem is, i dont get sub mini tubes very easy, so i try the ecc 81 and post my experience with them when i finished my special nano head

Hi,

i heard the ECC 81 tubes should fit ... is this right? I dont get 6021W tubes really easy, and for me its not so important that the tubes are sub mini type. So what you are thinking about this?
