Did the J201 work? It looks like the pinout is the reverse from the BF245.

I was actually thinking of using the 2N5457 as an alternative to the BF245B. The specs look similar.

Does anyone ha ...

AFAIK the plastic insulation itself has no shielding properties, it may change the capacitance between them but wouldn't shield them as such. If you want to bundle them together you could always do th ...

On Ken’s build page for the CGS01 he states;

Don't make the same mistake I did and tie all the wires going to the pots together. This causes some crosstalk. Either keep the wires apart, or use s ...

There is a problem with the Output Monitor module.

There appears to be a modification for the A-124 version of the Wasp filter which allows it to self oscillate (Soldering a 10k resistor in parallel to R13 (27k).

I was wondering if a similar modifi ...

Thanks Yves! I really love your modules. Thanks for all you've done for the community!!!

I resolved a bit of a nightmare problem with the Clock Divider;

The +15 voltage from R1/C1 doesn't go anywhere.

The board seemed to work (LEDs flashing and responding to rotary switches) but the ...

This turned out to be due to bad CA3080 chips that I purchased from China.

Thank you so much for the kind words Chris!!!

@AlanP - Thanks for the reply! I was thinking that was what they might be.

Almost 100 post views.... can anyone answer my other questions?

I'm nearing completion of my CGS01 but I've run into several questions which have put the brakes on the build. First I must apologize if I'm missing something obvious as I'm a new DIY builder with VE ...
