Rogue M-150

At this moment:
Input - GT 12ax7-M
Drivers - RCA Cleartops
Ouput - Penta KT-88SC (solid plate)
Sounds good to me.

Am using stock power tubes (EH KT88)
Stock drivers (EH 12AU7)
Input are NOS RCA 5751 3-mica (late 50's vintage).

Also recommended are RCA 12AX7 long blackplates if you don't want/like the 5751's.
According to Mark @ Rogue, the input tubes have the greatest effect on the sound.

Hope this helps,
Jeff

Thanks, I have some NOS tung Sol 5751. I will give those a try.
