Awesome, thank you.
Polyfuses huh, I haven't come across this component before. Every day is a school day though.
I'm off to read up on these polyfuses now.
Thank you again.

Thats delightful and a gorgeous looking synth! I had a good think and realised I couldn't be entirely sure of the provenance of the CA3080 chips I had installed. I had previously had LM3080s installed and the module still didn't work but behaved differently. This made me think that if the module is ...

Hello, So here are the images. As I said its all a bit of a mess now. I lost a few pads with swapping out the 2N4302 so many times. I had real bother with them as they were old stock with a blob top format. On one of them the plastic had perished and it wasn't working. I have since got these ones in...

Hello, Thank you for your reply. One of the things I tried was replacing the pot. I only had a 100K B but that made no difference anyway. I also replaced the wiring to the board at that point too. So I would say that area is quite sound. I'll have another poke around in the area where the wires are ...

Hello, Thank you for your reply. Both 120K resistors are installed. I have done the trace cut and reversed the correct transistor. Also just for reference the attenuverter is calibrated and seems to be working with zero in the centre as expected. Regarding the transistors, I have all 6 installed too...

Hello, So I have been staring at this thing for some time now and still haven't found a way of essentially broadening the the very narrow sweep area. Here is a picture of what it is like for Low and High Pass filters: https://www.muffwiggler.com/forum/userpix2/37507_screen_shot_20170905_at_140748_1....

Hello, Having some trouble with this build and was hoping someone might have a few pointers. It looks like I am having a similar issue to Emalot above. Essentially, the module works but the frequency knob only seems to have an effect from fully counter clockwise to about the 10 o'clock position. Wit...
