franzbassist Posted October 5, 2017 Share Posted October 5, 2017 (edited) New old stock from Karltone. Cost me £9.85 each, I'd like to sell all three as a job lot for £22. The JJ ECC83s (12AX7) is a high gain preamp double triode valve. Thanks to its design it performs with very low noise and microphonics. Harmonically rich with a detailed low end and a warm high end. Premium Tested on specialised digital and analogue testing equipment by Karltone as follows Gain (A) Transconductance (gm) Noise (dbv) Microphonics Emission Quality Grid Leakage Shorts Test results are provided on the box Edited October 5, 2017 by walbassist Link to comment Share on other sites More sharing options...
Sparky Mark Posted October 5, 2017 Share Posted October 5, 2017 Not sure that 3 tubes constitutes an amplifier? Should probably be listed in the other stuff for sale forum. Link to comment Share on other sites More sharing options...
