Here is a nice looking Fisher 30C preamp. Has original wood case and looks to be complete. EF86 is original and the 12AT7 and 12AX7 are 60s GE replacements that look new. I had my tech look at it today and it needed some signal path caps changed so we did that and tested it on the aux input and it works well on aux. We did not test any other inputs. Please ask ALL questions Before buying. Thank you for looking.
