RE: Questions about 6BG6G amp build (schematic) Grommes 216BA

I agree but look at the iron in the SP20.It is humongous and the amp is low power.All I'm saying is, Grommes used that output trafo with GFB and loop FB to the driver and much of that was probably to compensate for the output trafo. I havven't seen the OPT trafo in the amp but if he runs it at full power and bandwidth,he may run into problems.
