SB610 and manuals for AM1 and SB604

[John King]

Hello Folks:

Have sick SB610 monitor scope and no manual. Problem sounds like a ground
missing or open pot. It has dot on screen about 1/2 inch in diameter and it
is bright. The vertical position and horizontal position pots work and the
trace can be moved with them. The Focus control doesn't work, The Intensity
control doesn't work, the Vertical gain pot doesn't work and the Horizontal
gain pot doesn't work. So sounds to me like the string of pots are
effectively not in the circuit and are not varying the voltages to the
elements of the CRT.
WHAT DO YOU THINK??

I could use a manual for the SB610, also Heath AM 1 impedeance bridge, and
Heath SB 604 A.C. power supply for the SB 104A.  Please advise if you have
any of these and if you are willing to part with one or a copy.

Please reply via email direct. Thanks and 73, John, K5PGW
