I'm back for more Knowledge from the Fadal experts! Does anyone have a part number for the power transistors on a Glentek Amp -0008.This is a DC Amp from a 93 model 6030. The old transistors have a Glentek part number, GTK 45705. Nothing comes up on a google search. I called Glentek,and with much begging ,the tech told me it was a IGBT with 600v 50A rating. But wouldnt tell a standard part number. He did say that they have a new Transistor upgrade,part number GTK 45763. and the cost was 70.00 each!!!!! and he had 1000 in stock. There is 12 transistors on the board. I know that they can be found at mouser or digikey or somewhere for 4.00 to 8.00 ! Finances dictate trying to fix it till I can replace the amp with a new one. These old boards have very basic components,and most of them are user repairable, for a very modest price. The root cause of the board failure, was a carbon tracked set of brush holders, from years of poor maintanence and coolant ingression. TIA.
