Title: Moreplay build
Post by: Farvey on November 08, 2021, 07:10:51 AM

I am building a moreplay. I have come to the second stage of testing. My tubes are not turning on. Any thoughts?

Not having a Moreplay this is all I can do. Did you pass the high voltage test and the heater voltage test? If so what voltage do you get on pins 2&7 on the tube sockets with no tubes installed? If ok than what votage with tubes in place? Thats a good place to start.

The way you have your power transformer wired is not one of the options in the manual.

You also have 200 ohm resistors installed on the octal sockets which are not the correct resistors to use there.
