The shadow meter has continuity through the coil, and I recall getting close B+ voltage as discussed previously. From my understanding there should be a small metal piece, which is affected by electro-magnetic force of the coil, in turn resulting in the changing of the shadow dimension. Mine has no such flap. (It is the later style) Therefore, I am under the impression the shadow meter is not working, other than as resistance in the line. Ohms out about 1.5k ohms.

So, looking at the adjustment needs, is there a common start point I can use for all the variable caps which need adjusting?(The Ant., RF, and Osc. compensators) Sort of like when you tune a carb. on a car, you make bench settings, and go from there? Should I turn them all the way in and then back 3 turns, and then start tuning? I just keep going round and round with this...

Thanks!
Scott
