    Quoted from eh97ac:

    Thought I'd dig this up.
    My HV section went on my lost world and didn't have any 2n3584 on hand. So I found this thread and ordered up a 10 pack of BUX85's. The install is easy and painless, clip the middle leg and install like a 2n3584.
    I replaced the other HV parts, all caps and added some LED digital voltage readouts. Voila, a nice steady 190V.
    BUX85 were $1.11 CDN each after buying 10.

    NICE!!! How did you fasten the LED-voltmeters?
