[Collins] 32S-3 problem

[Al Parker]

Hi folks,
     I'm working at a 32S-3 for a friend.  Initial problem is that it 
"keys up" about 3-5 seconds after power up.  The finals go into idle, 
but no further.  I think I need to solve the key-up problem first.
     I've checked voltages and resistances in the vox/relay control 
area, can't find any problems.  Checked tubes, even substituted for the 
relay actuator.  Unplugging any tubes other than the relay actuator 
(6U8) tube will not un-key it.  Grounding it's grid doesn't help.  When 
switched to "tune" the finals' plate current goes to zero, but the relay 
doesn't drop out.  (the PTT switch is off)
     It's been a while since I've worked on a 32S-x, so I keep wondering 
what I'm missing.  Any thoughts would be greatly appreciated.
thanks, 73,
