AW: Need some help on selecting a good cleaning substance for a P CB?

	>2) The CA3046s are brobably bad: but they are in sockets (the
tempco resistor is UNDER >the chip) 

Under the chip, between the socket's legs ? *Very* good idea !!
(I always mounted them with long wires and bent them down
on the 3046 from above.  But in the socket must be much better !)
