Looking back to my pass experience with a 300B Pse
amp, aside from voltage swing, it would require quite
a bit of current to create a slam factor. Though I have
no experience with IT stage, I would imagine that the
IT used should be able to handle higher current.
The final front set-end up that I used for my 300B PSE was
a E80CC input with a triode strap EL84 driver stage.

# for jane :
This design was made for the KR-Audio’s T100 triode but it plays well together with 300B/842VHD etc. The IS transformer is 1:1 bifilar wound from Sowter (bw greater than 250kHz). With 300B and B+ about 500V the requirement for voltage swing from the driver is ~60Vrms (~85Vp).
With a triode like 300B you might like an OPT with 2.5-3.5k primary..
Please, can you republish the amplifier schematic with KR T100?
It is no longer visible.
Thank you
