1979 Sunn Concert Bass Schematic
« on: September 25, 2017, 02:04:55 pm »
Hi I'm looking for a 1979 Sunn Concert Bass Schematic. I found one on various websites but this one appears to be somewhat different.  Mine has a single bridge rectifier with discreet diodes, and the ones on the net seem to show 3 separate bridge rectifiers.  Mine also seems to have a 47k resistor and neon lamp in parallel with the main switched power supply.  Any help would be greatly appreciated!

There is no all on one sheet schematic for the later Concert Bass that I have found. This should be the power amp schematic. I have the preamp somewhere but I can't find it ATM.
