In the LFO, is C4 the wrong way round? The board shows the +ve side connected to -12V. Shouldn't this be connected to 0V, since 0V is more positive than -12V? I only ask because my C4 just blew up! :eek:

Just built a LVLS last night - probably one of the best build guides I've had the pleasure of using. Very easy and straightforward build. And the module is great! Simple but essential utilities...I bought it mainly for the preamp but the Attenuator has been brilliant for taming some of my chaotic LFOs.

I'm considering grabbing another one. :nana: Image

Hello,

I had to remove the capacitor 4.7uf for the lfo, because it stopped oscillating gradually. By connecting Pin 6 directly to the ground, no problem.

Hello,

Just obtained a few kits from this company and the links to the build guides are dead. They are also not available on Archive.org.
Does anyone have either a bom, build guide or even a picture of the guts? Honestly any help would be great. Thanks!

Thank you so much! A little over my head but that will help me learn more along the way. Again, thank you so much!

Edit: Bought the LFO and VCA from synth cube and nothing came with it and all links are dead. So thanks again!

Hi @fg could I ask a few questions about those diagrams for LVLS, please? I have one already, but would like another and it is impossible to get them any more so I'd like to DIY another one.
(1) On the I/O jacks, what does the 1@1*2 label mean on the norm pins? It seems to relate to the power connector.
(2) You have provided a modified Power circuit (the one you showed as "original" is also the one in the LVLS documentation).
(a) What do the 9*2, 3*6 and 1*2 labels mean?
(b) What do the floating 4 and 11 connections go to? Is that pins 4 and 11 of the TL074?

Many thanks for your modified diagrams and TIA for any help you can give to a noob!

Look at the image above (I modified it) with more explanation.
And yes the 4 and 11 are connected to the tl074
vcc + in 4 and vcc - 11
