Sorry - been a bit busy lately. My wife's been ill, my main desktop computer was fried by a power surge and I've had much too much to do at work - all have contributed to a lack of computer and workshop time recently. The wife's fixed, the computer's replaced (at the insurance company's expense) and work is quietening down, so I'll get on with some documentation!HEAD wrote:... otherwise we'll have to wait until mictester comes up with his pwm controlled cmos phaser.

i had a look at the pics,and thought to myself..."Geez,they don't make pedals like that anymore,don't they?",what vintage is that pedal?,looks like something from the 70's....

schematis I posted link before have correct audio part I checked that , in LFO there is only 10nF cap missing,pots for speed and depth are OK..... so...only thing is 4007 that has to be corrected.......HEAD wrote: Hopefully a schematic will follow.

I made that Schematic. When I got the pedal, there was no IC in place of the 4007. I was drawing it up on the assumption that it was a 4009, or 4049. That's why the schem looks drastically wrong. I still have the pedal, will pop a 4007 in there. If anyone has any requests, feel free to pm. I didn't spend much time on it. It actually phases with a 4049 in there. Of course, the 4049 has too many pins for the socket, don't know what I was thinking.....

Cool, how's about a correct schematic? Somebody should make the wrong schem floating around an end. With all respect, but having an cloned original layout is for sure a nice thing to have, but man these are unnecessary huge nowadays. Rm 10 for a poly cap? Who has that in his store and is willing to spend it on a phaser? Oo

Hi Nelson.....your incorrect schematic helped a lot for tracing PCB......I made drawing of LFO,Dirk changed it to blue .....and if you could make new correct schematic and post it here,it would be awesome!!!!!!!
thanks

Hello!!....lloo!!..lloo!...loo...lo... Nobody's home, don't worry, boys( I'm talking to the 5x4007 and 2xLM324 I have here; they're looking like ).askwho69 wrote:+1iq01221 wrote:¿And a LM324 in placement of the 3403?
Anyone?
Well, I'll try anyway, with sockets for ics... an maybe for all components .

Hey guys, sorry to ressurect the topic, I have one of those to true bypass, and the unity I have here have a LM348N in place of the 3403 and works just fine!
