In Reply to: Vacuum State DPA-300B amplifier - which transformer for 40W output posted by OliverC on December 25, 2015 at 13:00:29:
Hi,It's a good output stage, that's for sure .. I liked it.
The CCS tail forces Class A operation and as such you won't get anywhere That output power into the 5k pp OPT. 15 to 18W is about right.
Curiously, the Pdmax of 300B is 40W - but that is a different thing.
FWIW, IME the design is worth perusing.
Cheers.
