Any recommendations for a substitute for a 15pf silver mica cap?. For the FV-1 reverb board. Never got it to work and had a friend help me out with it and traced a potential issue down to the 15pf silver mica cap and there xstl. Unsure if I can use a ceramic equivalent for this board.
Thanks

I was slowly becoming a puddle of despair with this thing I swear. But now all smiles.

Solved the whine : )
Turns out it was the fricken' power supply. I tried 3 and then decided to plug into the power brick I have and voila. No more whine, and it sounds super cool. It does seem a little motor boaty so will swap out the pt2399's and see if that fixes that.  Big thanks to the members that helped out with advice and ideas. Now I can box this thing and enjoy it.

Thanks Cody, any suggestions are hugely appreciated. I just hooked it up with just the output and the whine is there in both the outputs and one at a time. It almost sounds like plugging output into the input jack type of whine. I was looking for the thread for the new wiring on this due to the ticking issue but could not find it. Is it possible I should have jumpered the J1 pads since I connected the ground from J1 to ground on J2 jack and ran input wire from J1 to the 4PDT (from the left of the switch: 3rd row?)

Tried pulling the IC's one at a time to see if the whine went away. Slightly lower in volume when they were removed one at a time. 2 at a time etc. Even there when all IC's were removed. Any suggestions?.

Audio probed this today and I hope I describe what I found well enough to help figure out where I should focus. Reading through what I posted seems random to me so apologies ahead of time if this all adds up to making no sense : )
DC jack: whine is present with multiple power sources.
Pots: depth/rate:clean no whine Volume 1: pins 3,2 whine is present. pin 1 clean. Fdbk,Sub,Mix1: pins 3,2 whine, pin 1 clean. Mix 2:pin 3 whine, 2/1 clean. Delay: clean. Gain: pins 3,2,1 whine. Tone 1: clean. Tone 2 : pin 3 whine is very loud, pin2/1 not as loud.
Volume 1 trimmer:pins 2,3
A/t switch top side of board left row and middle row :whine, far right row : clean
Q4: C=whine. Q1/Q2: clean
Regulator: input=whine, but not on output.
IC1: pin 1,2,3,5,6,7= loud, 8
IC2:pins: 7,8,9,12,14,15= faint.
IC3: same as IC2 but pin15 is very loud.
IC4: clean
IC5: pins 1=(loud),2,3,5,6,7=(loud),8
IC6 pins 1=(loud),2,3,5,6=(faint),7,8
S1 :square pad yes.
Foot switch pads on the board:R,O,R2,O2,S:whine.
I checked caps and resistors as well noticed certain ones were really loud. C6,8,5,27,9= loud. C54,32 =faint
D8 D9=loud. D3=faint.
Resistors that were concentrated around IC2and IC3 were quite loud as well.

                                             

Thanks Cody, I will see what I can discover.

So many amazing builds. Each one has inspiring and stand out technique and unique quality. Congrats to all of them.

Thanks for the ideas man. I rechecked the caps/resistors again, all seem correct but will do a one more go over just to make absolute sure. The whine is present in both modes, adjusting the knobs (speed,modulation etc) and the whine changes accordingly, speeds up, slows down, modulates, volume etc. I can hear the delay as well, it is clear and not distorted but the whine is clear as well, not distorted. I tried 3 different power supplies that work with other pedals. I will audio probe today and see what I can find. Needed a break from this one for a few days, it was frustrating.

I added the resistor but not the trace cut. I was ok with it cutting off if turned down completely. Would that possibly cause the whine?.

Any suggestions?

High pitched whine when effect is engaged. I had posted this before the big crash and had tried the suggestions from Jon in removing and adding a jumper to the resistor pads in line with the 9v in , and a few others . The whine is still there. I put back resistors I had removed. Replaced all IC's with new and same result. Wired for true bypass and used the corrected wiring for jack 1 was per updated build doc. No subs and here are voltages. I am stumped as to what do do now, so an S.O.S to the more skilled than me : )

I built reverb kit from modkitsdiy.com as a first build. Amazed it worked first shot, but I psent two days doing it sloooowly. Paul from DIYGP (his link is at the top of the page here) has some great kits as well. His 7 minute fuzz pedal is a great one. The crew in here is super supportive and helpful. Their advice on the audio probe and solder iron and everything is golden. Have fun man!

Thanks LaceSensor. Super fun build. Still need to wire up the pseudo-stereo jack but at least it's in there. Such a cool pedal.

I swear these pedals have not been turned off in since I fired them up. With the DOP and the delay/reverb going it's like a whirlpool vortex of ambient groove... like getting high, and I haven't been high in decades : )
