Heathkit VTVM
#20

I would say your V2 is not conducting based on what you have described.

I would clean the pins of the socket V2. Make sure the pins 1,6 have connection to the D1 and R29, and C6

I would check D1 and all resistors common to both sides of the V2 : R23 - R30

If I found no problems I would insure the transformer is putting out 120VAC not connected to the circuit.

Then I would start looking at and around M1.
