I'm restoring a Philco 37-610. I've replaced the larger 'lytics & have measured pin voltages, finding most to be close to the published specs, BUT the 6Q7 plate is at 208 Vs. 125!!! I certainly agree W/ Ron in regards the use of modern digital voltmeters rather than the low impedance equipment available back in the '30's... I have done some preliminary resistance measurements and found nothing pointing to such a high plate voltage. The 6A8 plate is near normal, being fed from a point near where the 6Q7 gets its' B+...
Has anyone out there seen this situation? I would appreciate it if someone having a working 37-610 would post their actual voltage measurements, or perhaps point me in the right direction. The set will tune a local station, albeit at fairly low volume. I'm lining up a source for the various small value caps & will begin to replace same, but like a former New Englander would venture: "If it ain't broke, don't fix it..."
