[Amps] Suggestions - I broke my amp

[Larry]

I am looking for suggestions regarding my Clipperton-L. The basic problem is that there is
no output. No apparent plate current.

I did several things:

1. I replaced the power supply board which seems to be working as the meter shows about 
2500V (I don't have an HV probe to confirm independently that there is 2500V). 
2. I had to fix the parasitic suppressors so I put in an AL572 RFC and suppressor board and 
increased the bypass cap to 0.001. 
3. I changed the plate blocking cap to 2000pf (from 500pf) and changed a couple of doorknobs 
for 160. The no output has been checked only on 20 and 15 so far.
4. I changed the filament RFC to an RF Parts RFCFIL30.

Some other facts:

1. The filaments are lit. 
2. The meter shows what I recall as roughly the correct plate voltage.
3. Using an ohmmeter there is continuity from the PS HV pad to the plate connectors. 
4. There is no plate current that I can see. Although, I once saw the plate current go to about
350mA and still no output.
5. Several years ago I added a tuned input board and there is continuity from the LVDC pad to 
input board and the bandswitch (unchanged in current mod but changed with the input board) 
still works correctly.
6. There is continuity from the plate to plate blocking capacitor and continuity from the "other"
side of the plate blocking capacitor to the plate tuning capacitor.
7. I rechecked the connections and still think everything is correct.
8. No arcs, blown fuses, etc.

I have obviously overlooked something. Suggestions?
