Vintage Simmons Drums (UK) Users Group

Is it possible that anyone has a schematic of this unit. I had oneof
these a good number of years ago & had the inputs changed to mic level
by a Simmons service unit in Florida - for $25!!!!!!!!!!

I need the schematic to determine the opamps, etc. I want to do it
again - I sold the converted unit - Duh!

Thanks!
