The JJ 12AY7 is another addition to the ever growing family of JJ valves. The 12AY7 (6072) are used in Fender Tweed amps, valve (tube) mics and to reduce the gain instead of a ECC83 (12AX7). They are suitable for all amps that use the 12AY7.
These are premium and tested on specialised digital and analogue testing equipment by Karltone as follows
- Gain (A)
- Transconductance (gm)
- Noise (dbv)
- Emission Quality
- Grid Leakage
