a copy of ken stones page:
Original and working WASP Filter, was for sale in end of 2013
...
In this build, you can see the correct wiring from freq. pot to -15V on power connector
Further Troubleshooting:
have connected the frequency pots to -VE and +VE instead of GND and +VE.
the groundwirings for other connections are connected further to GND.
one CA3080 from second Channel was faulty - 2 pins are damaged, after replacement same issue as before - LP Filter dont work.
after unswap the CD4069UBE the LP works, but without cd4069 no typical wasp vcf sound..
next step: ordering 2x new cd4069UBE oder HEF4069UBE (unbuffered)
