This one is now on the desk. The unit is pretty good shape, others some minor signs of liquid "ingestion" on the top panel. The unit looks stock, and I can see a few bubbled electrolytic in there.
All and all a nice build, with tiny input transformers on the 6 mic/line ins, and two output transformers on the XLR outs.
The owner says the EQ is sounds great when it works. The EQ is interesting because its a passive tone stack with tantalum caps.
How can we correct weak metalization in PCB plating?
Lots of good stuff in there.
