    1n5382b is a 140v 5w zener in an even bigger package. MCC and probably some other brands produce it still. It fits on the replacement SDB i make, but not sure if the original bally/stern SDB drill holes are big enough.

    Quoted from Quench:

    I like that you've used red and black wires for the C23 electrolytic capacitor - that's what I always do.
    BTW, what's the voltage rating on those two replacement green polyester capacitors at C27 and C28?

    The green dipped poly caps like that are usually only 100v rated based on xp.

    Color does not probably mean much but the red ones are usually 400-630v and good to use here.
