Have an odd one. The barrel converter for +48 for a crown pzm but the voltage on the pzm side is only putting out about 2v.

The schematic given doesnt seem to match what is actually in the barrel though. Did my best to trace out the actual board.

My understanding is im supposed to have 16-18v at the pzm end of the barrel.

Any thoughs?
