Tad,

Yes, that was the one I referred to, the shadow meter bulb.

With the other one, it was a matter of completing the circuit to ground to get it to light. You can probably get a replacement socket with a mounting flange at a nearby electronics store (it's possible Radio Shack might have something that'll work), or Antique Electronics Supply for sure would have something.

Chuck has more detailed info on resistor wattages, but I can tell you the majority of resistors are 1/2 watt. A few in the power supply section will of course be higher. Avoid using 1/4 watt resistors on stuff this old.

Good luck!

Bill

I think this thing is way more accurate than my Walmart DMM. :DStormlord5500 — 08:19 AM

Thankyou for the kind words sir. I double checked it with my component tester and it read 2.7 ohms at .02mH.Stormlord5500 — 08:14 AM
