NLC SPASM

 Seven way Vactrol for NLC SPASM , beautiful module ,my layout is correct ,i used film box for the ldr's 

modular bleeps

I found this recording not long ago ,it is recorded in 2012 - November or so , and it's only survived recording from my first modular synth ,it was mostly done on stripboards ,while the panels were found materials and even cardboard, i reused pots from an old mixer for this synth a lot ,they have proven to be very good quality , one of the panels for artwork has the record sleeve of a rolling stones album

VCF1 3521 PCB2

 This is double sided board for EFM 3521 VCF ,it is suitable for 4U format ,i am yet to build it so i don't know if there are any errors in the EFM document that you can find at Fonitronik's site , i used mached BCM847/857 transistors ,the PCB dimensions are 140x55mm

Radio

 Beautiful enclosure from an old radio ,suitable for a Modular ,9 x 13 rows of functions is my calculation

VCF 1 3521

 This is descrete version of Oberheim SEM Filter ,it is from the EFM Schematics for VCF1 3521 , i replaced the transistors with matched BCM847/857 pairs
