This is a suitable replacement for any 12DW7 / ECC832. One side has a gain factor of 100 - the other side has a gain factor of 20. You can think of it as 1/2 a 12AU7 and 1/2 a 12AX7. Try this tube for some interesting gain reduction effects on certain amps.
Please Note: Due to the fact that the 12DW7 has two triodes with completely different gain factors, this tube cannot be balanced.
A. F. twin triode with separate cathodes, non microphonic
