12Axx/ECC8x vs industrials
Posted: Sat Mar 16, 2013 1:41 pm
I had to get three ECC82/12AU7 for a preamp but bought 5693 (GE) instead. Not believing that numbers on a tube makes any difference, I still must confess that I am curious - is there any difference between "standard" audio tubes like 12AX/AT/AU... aka ECC81/82/83 ... and their respective "industrial" types?
Russian tubes can often be optain with an added -E or even -EV, which signals that the tubes are mechanically more stable, but can I expect something like this from the 5693?
