I have been looking at various bias supplies for the 2sc2879 transistor.
I am going to run 4 of them in my amp. An appealingly simple diagram shows a
7808 (8v @ 1 amp) regulator supplying bias for a pair of these transistors.
Anyone with any experience with this sort of set up? I could easily put two
7808's in my circuit to feed the center tap of the input transformer to each
pair of 2sc2879s. The circuit I am looking at has an output resistor on the
7808 of 8.2 ohms and a choke in series to the center tap, and also two
resistors shunting one rated 1 ohm the other labeled TBD (is that to be
defined?) This is on a Telstar Electronics schematic for what is identified as
a Skywave 2879AB.
Any comments about this arrangement?
Thanks
