- I have a toroid here which came from an AL811H amp. It was used in what appears to be an rf feedback ckt. It is about 2 3/8 in. OD. and about 1 1/4 in. ID.and about 1/2 in. thick. Dark gray to black

- One can tell by tapping the core with a screwdriver. Ferrites are hard like glass or ceramic, and they make a tink when tapped. Powdered iron is softer. Also, some ferrites have resistance and powder

- Thanks. Real amps don't have more than 2 tubes in parallel, <g> so no loss here. Collins made one too. Bill K2AME

- Two tubes doubles the feedback C, so mo' tubes means less vhf stability. However, since doubling the number of tubes halves the RL, double the C-tune is needed to maintain the same Q. it should be d

- Hi folks. A technical question for a change. I replaced my 3kva singel phase HV transformer with a 1100VA toroid transformer.(output V is the same) The voltage drop is 300 volt less with the toroid t

- --The toroidal core [a.k.a. Hipersil] core is so efficient that transformer loss is essentially the copper loss. In a conventional transformer, core loss is similar to copper loss. Toroidial hv tran
