Telefunken ECC801S / 12AT7WA

1 Review
USD $‎349.95
The rare Telefunken ECC801S tube (12AT7/ECC81) is thought by most to be the best 12AT7 tube ever made. Telefunken stated it would last 10,000 hours or more. It is very robust and has a super quiet filament so hum from the heater is greatly reduced. The Telefunken ECC801-S tube's construction also includes triple mica spacers which will further help reduce microphonic noise. Like all authentic Telefunken preamp tubes, the diamond logo is molded into the glass at the bottom of the tube.  This batch was produced in Ulm, West Germany in the early 1960's.

Note: Some of our stock is in original boxes but others were from a bulk case and we packaged them here. However all are true NOS tubes.
