RE: [motm] 110 VCA/RM Troubleshooting

2001-07-25 by John Potter

So should the CEM chip sit absolutely flat on the socket?  

Mine sticks up by maybe 1/2-3/4 the thickness of a dime.  Anybody else have
to bend the legs in a little bit to get it in.  W/O doing that there was
absolutely no way it was going in by itself.

Thanks,

JP

i had the opposite problem when i built mine: the ring mod woudln't work.
after much head scratching and circuitboard-peering, i noticed the 3330
was sort of off kilter. i reseated it and ring modulated crap all through
the night... another feather in the cap of the "sockets suck" argument.
