Problems with Space and Time Reverb

[GiulioGratz]

Reverb and mix at max: no signal.
Reverb at min, mix at noon, tone at noon and i have the f*****g best sounding tape delay ever  really, i could play for a week without stoping with the delay part of this pedal (i'm going from delay to overdrive to AMP... Never heard something like this, really)
And the percussive sound is gone! Have i bad soldered the btdr socket?
Thank you for this design, really, it's so beautiful sounding...

OK, your PT2399 seems to be working, but your reverb brick is not connected correctly and/or there is a problem around IC2A and/or lug 3 of the reverb pot.
Also, the regen pot should change the number of repeats with reverb at min - does it?

>i have the f*****g best sounding tape delay ever

Thanks, but wait until you can mix in a little reverb!

If i connect the btdr i return to the percussive sound side. The regen pot becames unusable. There is a big drop in volume every period of the tremolo effect, i'll check also reverb pot, ic2a and the brick connections

Can you check the reverb brick works by breadboarding the circuit in the datasheet

e.g. something like the mono circuit here:  http://www.accutronicsreverb.com/main/?skin=sub01_05_1.html

There is something very frustrating here... Yesterday i tried the brick with a chasm reverb that always gave me problems and it worked! Tried again this evening and it worked again until it started to make some bad noises...
But it worked more than 1 hour continuosly before making bad noises, so i think the brick is good!

Also the story of chasm reverb is weird... I can't figure out how to make Work theese reverbs other pesals are always ok, don't know

I have heard a few stories about BRDR bricks that people have killed with too high voltage supply. Haven't heard of one that has an intermittent problem. Can you measure the voltage on the output of the voltage regulator before after it starts making bad noises?

[GiulioGratz]

Ok... Tried yesterday the chasm for two hours... Never had bad noises  so i didn't measure the voltages...

Space and time: i resoldered the btdr socket. It is as it was before: with btdr -> percussive sound; without btdr best analogica tape echo simulator ever... But i want a reverb ahah not another delay double checked again all the joints, but always the same story...

Great, you have either  a wiring error to the BTDR, or more likely, an error around IC2A - check for shorts under R14, R15 and/or a wrong value for R14-R16.
