Also another shop had a Mullard ECC32 which the chap assured me it was compatible to the ECC35 but just older & a globe shape instead of cylinder. I didn't want to take the risk of buying it first but thought I'd check with you folks. Can anyone confirm if I can use the ECC32? It's supposedly a 6SN
The info didn't sound right to me but I'm also a noob at tubes.
They're quite different...
6SL7/ECC35 is a high gain tube, while 6SN7/ECC32 is a more moderately gain tube.
The heater current of ECC35 is 0,4A
While ECC32 s 0,95A
Often this part limits it's use... If an amp is made for 6SN7 it's possible that 6SL7 can be used (lower current-needs) however, 6SL7 can be operated at higher voltages, up to 550V while 6SN7 is limited to 300V.
In short... Under some conditions, 6SL7 can be used on 6SN7-amps, however, there's quite a difference in gain, which might make the volume pot unusable.
Hope it helps...
