    I hope someone can help. I need the parts number for the three Mosfets on the Valvestate 8100. Two large ones one small. They are mounted on the board and large heat sync in the amp. On the board they are marked TR8 TR9 TR10.

    Your help is appreciated.


    Thanks
    Dave

    TR8 = BDV65
    TR9 = TIP29C
    TR10 = BDV64

    Not trying to split hairs but the power transistors are not MOSFET's they are Darlington transistors.
