Hi Jeff. I've had the HOT in stock for a while so I can't remember if it
was a cheapie, but I haven't run into any problems like that from the
place where I normally buy them. I'll look through my HOT stock and
maybe find something else I can try instead. Eric has suggested that the
B+ at 139.5V is a bit high (135V is normal) so I'll adjust that first.
BTW Jeff, I keep getting messages that my mail to you is not being
delivered but they keep trying to deliver it.
