I converted an MLA2500 to a single 3CX800A7 some years ago, and it works fine. If I was doing it again I think I would probably use a pair of GI7Bs which are much cheaper. I don't think you need an extra filament transformer - the existing transformer has a 12V 4A winding which is plenty. (As others have mentioned, the voltage will probably be too high and a series resistor is called for.) The 6V winding can then have a voltage doubler on it to supply relays and and LEDs. 73 Roger VE3ZI _______________________________________________ Amps mailing list [email protected] http://lists.contesting.com/mailman/listinfo/amps |
