Substitute for 2SK3497 and 2SJ618
After a looong wait I'm about to build the F5X.
I'm looking for 2SK3497 and 2SJ618 for the Power Supply, but they are not easy to find now. I prefer to by things from DigiKey and found two Mosfet that looks ok on the paper. FQA28N15 and FQA36P15-ND.
Does any one have a better choice?

The R101 is burned. In my haste to get the amp up and running, I've connected the v (-) filter board wrongly. The rest seems okay. I've test the board with lab supply and it still work. Will this affect the biasing?

glad you did It

Thank you. You should build yours.
Backplane connectivity
Since we were under the impression that the rather wild wire routing and loosely mounted components at the backside of our first amp would not be an adequate permanent solution we designed two backplane boards ...
