Very much appreciate answers from far and wide. On use of my scope which seems good enough for the purpose, an old 60 MHz Tektronix, I see a very small signal on the "freq" test point but nothing on pin 8 or 10 of IC3 and with a magnifier see nothing amiss with the solder joints of IC1. Completely redid all solder joints, see voltage fine at 20 and 7 on IC2. Leaves me at a loss. Hard to believe how it all disappeared given the very straightforward testing and alignment it went through just fine.?
