Hi all.
I made a template for the new Chop Shop with tone switch since I couldn't find one. I have not built this. I have not ordered this. I'm pretty sure it's correct, but I am prone to some silly errors. Please check my work and buyer beware until I confirm with an order. Note I use 5mm LED...
Good grief - thank you so much for the corrections. I had misread the discussion on freestompboxes re: the voltage divider.
Any thoughts on the volume control? I'm thinking of just leaving it at the Termina values since I think it gets to basically the same place. OTOH, if I used the Jan Ray...
I've had a few real Timmys. I'm doing this version just to see if I actually notice any differences...plus it amuses me to do a clone of a (mostly) clone of a great pedal. Thanks for your thoughts. I'll check out the TSV-808.
I'm wondering if anyone has used the Termina PCB to create a Jan Ray clone. I'm starting with that PCB rather than the Tommy as a quick look (to me) suggests it's easier to change the values to match the Jan Ray schematic.
I've compared component to component and it seems pretty...
Well....don't assume I'm a he and can see very well ;) (I am and I can't thanks to a couple of retina operations....probably shouldn't be soldering small pads with hot irons...haha). But, I was thinking about your suggestion too. I think I should invest in one. I did find the bridge....late in...
Ugggh…careless, thine name is me. Solder bridge on IC2 that I missed first time through. All is fine now. 🤦♂️
Agree on the solder joints. This was my first project from PCB. I’m getting better, but still not there.
I’ll add larger ones And bend the pots. I swapped a new 10K for R17 and my desoldering methods needs refining. I figured it might be the problem since the voltages go from 9.08 to 0 across R17 (still do after swapping). Anyway, the leads are connected to the pads…poorly, but connected.
The side...
C13 replaced. Still get continuity across the leads :unsure:. My voltage is not dividing correctly (Vb not 4.54V), so I'll go back to R17 and R18 to see if I can get them straightened out. Pin 1 and 4 on both ICs read correctly (9.08V and 0V). Pin 2 and 3 on IC1A operate correctly (pin 3 V 1/2...
