Default Driver transistors in a Punch 150

Anyone know of a replacement for the d40d8 and d41d8 drivers? Got one of each shorted.

Those have been discontinued. The CENU07 and CENU57 should work if available. Some of the members here may have NOS parts that they can sell you.

It's also possible to use TO-220 transistors if you shift them over to the left and use a jumper to connect the emitter to the board.

For testing, you can use the MPSW42 and MPSW92 or even the MPSA06 and MPSA56.
