    I have misplaced my chassis screws when I tried a new rectifier tube out, can some on tell me what size they are so I can buy a bunch?
    Thanks, Nut

    The screws that hold on the parts to the chassis are 4-40 stainless steel machine screws. Those screws that hold on the bottom cover are 6-32 stainless steel machine screws.

    I got some phillips head screws, I found the surest way to scratch the shinny chassis is to use flat head.
    For me, the screwdriver just slips through the slot and the results show.

    Understand your aversion to slotted head screws, but you don't tighten/untighten them that often. My vote is for you to use 4-40 Binder head slotted screws...I'll go with Phillips myself!
