Home Tube DIY Asylum

Do It Yourself (DIY) paradise for tube and SET project builders.

Old design detail on PPP tubes.......

I noticed organ amps from the '40s & early '50s using plate inductors on parallel PP tubes. Both Hammond Jensen & Baldwin use a plate inductor of 1/4" diameter x 3/4" long with 20 turns on just one parallel tube plate on each side.

Any comments?
