Closed and moved to Ebay. I originally ordered this from Tube World to roll into my Evil Twin DI's, 12AT7 position. I have never used it. I have a Telefunken ECC801S in place now, and other website descriptions state the Siemens E81CC's are nearly the same sonics. This would be a superb preamp tube. The Tube World description states: 1 platinum low noise tube, E81CC=12AT7WA Siemens NOS, triple mica, copper grid posts, 1971, original box (Gm 2075/2125) A small portion of the lettering is worn off The tube resides in the Nashville area. No trades, a deal at $80.00 shipped USPS CONUS. Paypal works.
