RE: Questions about 6BG6G amp build Grommes 216BA - pic




That is, of course, the problem (of several) using old schematics as a guide. One can't fully know the old iron used, and what compromises were made to work around the iron's specs/shortcomings. A picture of the amp shows BIG OPTs. Mine are smallish, from Hammond organ amp. I used them in a previous build so they sound full range.

Tube data shows 6BG6G in class AB1 - 450V anode, 400V grid2, -37V grid1 bias, and 5.6Kohm impedance on OPT. So that was sorta was I was going for.

Thanks for info,
Pete
