Drawmer 231 Compressor/Expander

I have scanned the circuits for the above which I will post if anyone is interested. It uses a discrete VCA with indiscrete discretion!

Interested to see that VCA.... Is it the same as the DS201 gate?

It sound very good , because i do know the ds201 with its special fet , difficult to get , so i do hope that the parts are easy to get.

Please could you send me a copy of it at htgerbenzon(@)hotmail(dot)com

I don't know which FET is used in the VCA section - I dare say Drawmer leave it to one's imagination!!!

Old thread, I know. But for the record, it´s a 2N4391 FET. I finished repairing a DL231 a few minutes ago. The problem was one of these FETs being half-working.
