  The first thing I did was call AVA. They did not have any spares What is your price for the parts unit and how much shipping to 21136?
  Thanks

      Sorry for the delay. got caught up in a painting project.

      This unit I built from a kit back in the mid 80s and ran it for a bunch of years then a friend blew it up. I then used the chassis for "Dick Smith" MOSFET modules and in the last few years ClassDaudio modules.

      Let me know if this is the correct switch.

        Thanks for the picture. I have the narrow switch. At this point I am using the amp with a remote controlled switch.

        The slot for the power switch on the ST150 is narrow (as the OP mentioned above). This picture is from US Audio Mart, but looks like the ST150 I owned and used all through college. Any replacement switch will need to fit that slot.

          That's why I posted a picture of the power switch. Mine is the reissues from the 80s. Looks like the switch in mine won't work.

        I built an ST150 in the mid 70s and eventually blew it up too playing with the power supply. But before that when I picked the amp up I asked about adding power supply capacitance and was told by Dynaco the more the better. When told you could squeeze 8 caps in I bought 6 caps and it worked for years. The 1st problem was the on off switch finally gave in probably due to the extra on surge of the extra caps.
