Re: Danelectro - BP-1 Pride of Texas [schematic]
I couldn't enhance the picture enough to get an idea about how the bass pot works. Any clues?

Re: Mad Professor - Simble [traced]
What's the purpose of those parallel caps? C12 & c13? I'm asking because if you connect c12 to accent 1 and leave c13 as is...it works as a high presence filter. Did someone try this?

Re: Split transformer x2 +9v outputs
Ahh...ok. i was trying to get 2 independent 9volts outputs as in an isolated supply. Thought would be possible using a similar approach but using the coil tap as a common and rectifying the outer leads...in a 9+9 tranny...

Split transformer x2 +9v outputs
Hi. I've tried to post in the power section but seems closed. Can i have 2 +volts outputs out of a split transformer using 2 bridge rectifiers and a common ground?

Aion lab series l5
Hi. Just finished this project and i am having problems with r76. Before it, i have audio probe and tested the 4.40 ac volts as per calibration. Right after it, audio is almost lost and ac volts drops down to few millivolts. Any clues?

Re: Dunlop - JHF3 Band of Gypsys Fuzz Face [traced]
do you guys know why they've chosen a 220k resistor inthe cathode follower stage?. it seems pretty high. the original had 22k in there.
i also think the last resistor is 10k. but it shouldn't be calculated as an isolated part...because it's part of a 2 pole low pass filter formed by r12,13 and c9,10.
