Thank you. I checked on the Philco Service hints page, when it was still up and resistor 47 was rated at 2W. I have a pair of 2W in parallel, which should give ample wattage. Resistor 15 maybe should be a 2W however it's part number wasn't listed. I think I will order a 2W flame proof, just to be sure. I did check the voltages on the 6A7, with my VTVM and they measured right at what they are indicated in Riders. In the past I have seen some of the older oscillator/detector tubes do some strange things and still test correctly. The only true tube test is to substitute it.
