John-


I use a Chinese Sonicgear amplifier for my PC. It actually uses one
ECC82 / 12AU7 tube for preamp. I replaced it with a NOS Tungsram E80CC
and never regretted that. The improvement in sound is unbelieveable.
But be cautious: may be the E80CC can replace an ECC82 only for audio
but not for driver.


The e80cc is neither a 12AU7 or 12AX7. See it here-

It is spec’d for digital applications, specifically cathode interface
caused by long ‘OFF’ periods. Should be AOK for audio!

Cheers to all, John L Stewart
