CTC-4
I could use the help! Checking voltages on some of the various tubes show something else is amiss as many pin voltages are way too high--perhaps a bias supply problem?--and a few about 10-15% too low. Hmmm. I ran into this with my first 621-TS; a number of voltages were off but the set works fine. Odd. Must be a designed-in variance, huh?
