NOTE: Though not as refined as the earlier production from Rožnov n.p. Závod Vrchlabí plant we had earlier (click here), these Trinec plant tubes are still quite fine. No refunds, exchanges or tube rolling at our expense as it says in the Terms and Conditions on the web site. Nobody can guarantee how any tube will "sound" in your system.

Brand new, MINT NOS Original TESLA E83CC* Frame Grid Tubes - Replica of the famous Telefunken ECC803S Frame Grid tubes. All tubes from the same batch of OCT. 1991 made by Rožnov p.R. Závod Trinec. E83CC is a Premium version of 12AX7 ECC83 with low noise, and low microphonics. These tubes are very quiet and musical.

 

Same internal construction as the Vrchlabí plant E83CC with two getter supports (JJ has only one). Production of E83CC and other small signal tubes was moved to Trinec after Vrchlabí plant was closed in 1980s.

Tested and matched on Top of the Line Calibrated Hickok 580 Lab Grade Tester recently calibrated by late Chris Haedt. 65% = 1000 mmhos for ECC83/12AX7 on this tester.

Price = $65 per tube. If you order 2 tubes, we will send you a matched pair. Odd number of tubes will also be matched.
