I have had this 5F1 kit for 2 years and this is the 3rd time I have stripped it out and started from scratch. I have completed the build and everything checks out up to installing the 6V6 power tube. There is no filament glow and the DC voltage on pin 5 of the power tube is 29 VDC. According to the manual it should be 0 volts. All other voltages are checking a little high. I would appreciate any help and suggestions as to where to look for the problem.
