Griffin Ricochet (Surfy Bear Clone) Issues

[Brandalones]

I just finished a build of the Griffin Effects Ricochet (https://griffineffects.com/byo-pcbs/modulation/ricochet-pcb) using the original mixer, and am getting power and signal in both bypassed and on positions, but when on, I don't get any reverb, only like a fuzz when dialed wet. No crash sound if I shake the springs either. I had the TP1 getting voltage at about 6.6 after adjusting R13. I also read on another post that someone tried removing Q3 - BC557B so I also did that. No real change.

Any ideas what else could be the issue? My only thought is maybe one of the MOSFETS are fried, but I am getting voltage readings on both of them. I don't know what they should be reading at each pin though.

You guys got any pics if your pedals? I got this one on the way and im debating the tank set up. Right now im leaning towards just mounting the tank to a piece if wood large enough to velcro the pedal to

the surfy I built is in a tool box because I used the long two spring tank. the ricochet was in an ammo can with the shorter three spring tank. frame of reference, the toolbox will fit a full size amp head, the ammo can will fit the smaller "lunchbox" size like the OR15.

I haven't housed mine yet, but I have another one going to a friend, and he already built an enclosure that's slightly smaller than a Fender 6g15 unit to mount his in. Mine will be closer to the SurfyBear form factor.

Thought if i could find an old empty head cab

Big thanks to ITC and Earl...replaced R15 with 1.5R and lo and behold I have reverb. Q4 and Q5 are hot. Voltage at the TP1 is about 8 volts, so I need to adjust the value of R13, but headed in the right direction now. Thanks again!

For MOSFETs, it is necessary to install additional heatsinks so that they do not overheat. By changing R15 to 1.5 Ohm, the BIAS current becomes 400mA, which results in a power loss of 0.4Ax6V= 2.4W on each transistor at the set 6V center voltage. Therefore, it is necessary to conduct 4.8W of heat to the surroundings, for which the copper polygon on the printed circuit board is insufficient. I suggest an Aluminum L profile that is screwed to the metal housing. Of course, it is also necessary to take care of the electrical insulation between the transistors housings and the aluminum.
