[Amps] Nat NCL2000

[HOWARDLYON@aol.com]

Hi guys
 
Trying to renovate an old NCL2000.  Hadda shotgun the doubler  board.  The 
caps were teenagers with pimples and whiteheads  everywhere.  The dividers were 
all outta spec... 75k to 120k!~!~!  New  board is 12 pairs of 68uF/450V/105* 
radials (about 11uF/5+kV) shunted by 12  100k/5W; new bypassed diode stacks; 
Dale 25W heat-sinked limiter resistors; on a  3/16 XX phenolic board with 
grommeted mounts and silvered test pin  connections.
 
Replaced the caps in the grid supplies.  Replaced and bypassed  alla the 
diodes.  Replaced the smoked HV control relay.  Made the  wiring change to the two 
75k bleeders.
 
The screen supply txstrs test OK, but the resistance measurements through  
the network are all well beyond 10% out.  Anybody ever notice this?   Any ideas?
 
What is the ALC output?  My IC746 accepts 0 to -4V.  The circuit  looks like 
it puts out much more than -4.  Attenuator time?
 
Thanx fellas.
