hey guys, finished mine a few months back, took the extra time measuring components as well as i could and working with the xls, and seem to have come up trumps. carrier bleedthrough is for all intent ...

13k resistors get me unity gain again....rofl

thanks for your time and patience jurgen Smile

cool, im going cross eyed trying to find something thats out of place Smile

i have set the offset trimmer to mid point so its a bit easier to see what is happening now (the tl071 has been set up as a differential amplifier, right?).

On a statically selected stage, varying ...

i had to get a vishay as i couldnt find the tt's in 1M, and they are noticeably lighter than the vishay. i like it but ymmv.

I have set up a static test case where a constant 5v voltage is fed into the 9th stage and this stage selected with the manual control, and recorded the voltages im seeing around the tl071 and relevan ...

hi jurgen

r79 measures up as a 1k, checked the other resistors and they all look right too.

one thing though, the offset trimpot, is that part of the lfo? i assumed it was and as i didnt have t ...

hi guys

having great fun with my pair of scanners, but there is one niggle....seems the output level is down in the line level range rather than the +/-5V modular norm. for example if i send a set ...

cake?

first two layers are power filtering (beads/caps), then its the switch to send in a standard voltage to the...erm...forgotten the damn word...the normalised/unplugged inputs of the jack ...

about the living vco layout....

there is a contrast between the top-down a-b-c of the fm/det/pw/pwd controls, and the big freq knobs, which i laid out in newspaper style

-B----C--

...

you want the fpd? no problem.

i spent a while playing with the layout. quite a bit of time actually Smile

for reference the small knobs are 16mm, the large 27mm, and the knobs behind the panel are ...

a nice panel can hide so many sins, cant it?

and my interpolating scanners...

(both modules are eurorack format, 15v supply)

My living VCO...

there is another identical one right next to it

lovely stuff jurgen, lovely stuff Razz

further to the above, i have managed to monitor the modulation signal just before it goes into 4011 chips by using probes and sending the voltage to the fm input of an e340 sine wave, and can hear the ...

hi guys

just built one of these triple choruses, and am having an odd issue. i seem to be getting a lot of highish frequency hash/buzzing in the output that sounds unpleasant.

when listening to ...
