[Amps] AL-1200 Questions

[Dana Roode]

Folks -

My AL-1200 repair efforts continue.  As you may recall, the parasitic 
suppresser came unsoldered and I had some sort of oscillation in the grid 
that took out the grid resistors, a resister in the grid meter, and my 
756ProII.  It turns out it also took out my ARB-704 relay buffer, and last 
weekend the grid meter mechanism itself gave up the ghost.

Questions:
- After replacing the grid resistors, the resting plate current seems too 
low, maybe half of what it should be.  Is there an adjustment for this?  I'm 
not sure why it would have changed.
- I will order a new meter, should I put a diode across it to protect it in 
the future?  What kind?
