Very sorry to hear this. Larry was a great guy and a class act.  RIP buddy.

The exciter has no effect on the buffer meter reading. Nor does it effect the oscillator meter reading.
I will take the aluminum cover off tomorrow and check out the contacts on the band switch.

If you have ground rods connected to your station ground buss, you must connect your station ground system to your AC panel ground with a heavy copper line.

Does the "Buff" reading change on the Valiant meter as you tune the Exciter control? It's just as if the driver tank isn't getting to resonance.

Are the wafer switch contacts clean for the bandswitch switch under the aluminum shield?  It should have several wires of different colors connected to it from the driver tank coil.

Yes thanks, I did that in fact tried all the positions for the RF reading at the mica caps but no change. I wonder if I should try it with the oscilloscope?
You think the micas might be the suspects? - I think I saw them on the freeway in a white bronco.

So I thought this thru. I thought why not build your circuit and learn from that since I know it works well. I can go rouge later. First I need to kmow how to do it right. I thought back on my days building race engines and helping others learn. Many were always trying to improve or cheap out. Those who listened and psid attention did well. I decided to draw from that and learn from you.

That's about right for voltage. I should have mentioned that the Oscillator switch should be set to "Zero" in order to get proper RF at the mica caps.

Okay Clark,
I show 356 volts across C7 in AM on "ZERO" position and 377 volts on AM on "VFO" position.

I noticed that issue too, that cap is kinda stiff to turn, but yes, it is opening and meshing the plates.

By slipping I meant that the knob is actually turning the cap. It just seems like you're not able to get an RF peak on the meter which suggests that the tank circuit isn't getting tuned.

That cap will have 300 volts on it, full 5763 plate E!

We're basically testing the tank circuit connections...
