the ECC32 is the best overall sounding 6SN7GT replacement; the ECC32=CV181 is NOT an
exact electrical equivalent to a 6SN7GTB and should not be substituted for a 6SN7GTB
if the plate voltage is over 300VDC and it may not work well in some applications
where the negative grid bias is too high. Also, the ECC32 requires 950ma on the filament
verus 600ma for a 6SN7GTB, but this tube has a glorious rich midrange,
smooth and open top end, with very good bass articulation, music sounds real with this tube
