just wondering if I can use a OC71 instead of the OC44?

thanks for the response! I will check this! maybe at the end I will get one (a lot really) from Small Bear!

well... I kind of solve the last problem where all I can hear was Hum... but now I have a new one  when the pedal it's off the signal go trhu but when it's on it mute the signal and I can hear anything!... what am I supose to do now! where do I start to check where the problem is!?  Hoooo and BTW I coldn't find the OC44 so the guy in the electronic store gave me a A144... maybe this is the problem or is this transirto equivalent right? thanks!

... the last one

3rd one

another one

these are the pics! help please!

Well the way I did all the wiring was just like the description on the rangemaste manual! is there any other wiring missing on the manual or that I should do?

Ok, thanks for the info... I will be uploading some pictures in the afternoon! and by the way I'm powering the pedal with a 9V baterry!

Hi, I just started on my PCB of the rangemaster got all the parts on the electric shop avalible nervy my home and start all the thing...I don't know the first thing from electronyc but a friend of mine is helping me out! at the end I end the project yesterday and try it today... sad for me... didn't work! so now what am I supose to do? where do I begin to check or try to find where the problem is?  I just plug the instrument cables on the jacks and start make it a lot of noise and hum even whit the pedal off!? does that mean something?

  Thanks for the information... I'll let you know how it works! 

So I buy a Board to build the Rangemaster from here, but I can't seem to find the capacitor the C1-5n; C2-22n and the C4-10n... I found some of them in a electric store but not in the same shape as the one in the photo on the build section in the photos, mines are mor in the shape of Ceramir disk, will this work whit the project and if not where can I buy this caps online!? thanks!
