Philco 16b-Measuring voltages
#5

The resistors will be getting changed over the next 2 weeks. I found enough out of spec that I ordered a complete set of what I need and will simply replace all of them. One problem is that the schematics show the 5YZ as rectifier and my model runs the 80. Voltages are a bit lower on the plates. The directions didn't have much detail to them. I have my 1st AF showing 45 on the plate and it is spec'd at 130, and I have my AVC showing 45 on the plate and it is spec'd at 1.8. The other plates are all on target, so I'm guessing I'm doing something wrong here-that's why I asked. Even with the original resistors in it, it is really a great performer.

I just don't understand why Philco radios had voltage charts set up like this. It doesn't make any sense to me.

I'll replace the resistors and record my voltages. That way if there is a problem in the future I'll have a baseline reading.
