[Amps] Alpha 77SX forward & reverse W not working

[Gary Smith]

Another hiccup in getting this old girl 
back into shape. I rarely use the watt 
meter in the amp, I use the one in the P3 
and on top of the amp is a LP-100A, those 
always handle my needs. As a general rule 
I leave the multimeter in the Grid setting 
and always use that.

When I had a look see in the amp to see 
what was what was going on with the 
padding caps, all seemed to go well, no 
unexpecteds happened but with reassembly I 
tried using the watt meter and found it's 
barely working; the meter moves but very 
little. The last time I used it 4-5 months 
ago, it worked well.

No telling if I somehow bumped something 
but is there a likely first thing to look 
at? The meter movement is fine, works 
seamlessly with grid current.

P.S. I received all the new  High Energy 
7.5KV 9A doorknobs to replace the old 
Jennings and Centralab 1A variety. Waiting 
for the Ameritron choke and some silver 
plated flat wire to come in and I'll get 
them installed. It'll be nice to have the 
tank upgraded.
