RM9 won't turn on - switch?


My RM9 won't  power up.  I pulled the bottom covered and didn't see any mainline fuses.  Is the switch the likely culprit?

Yes, there are 3 fuses. 2 (1A) fuses (probably in the bias circuit) and a 5A fuse which probably is in the filament circuit. They looked good but I will check with a meter.
The filaments don’t light which is why suspect problem in the mains.
Yup.  Checked the power switch with meter and it was open in both switch positions.  Its a MkII, found some switches on Amazon but had to buy 15 for $7.  Must be really good at that price.
