Today the IC sockets arrived and soldered them all in nicely.
Inserted all chips that have arrived new except for one which I am still waiting for.
PCB is nice and clean and went through it with magnifying light with fine tooth comb for bridges,cold joints or broken traces.
Powered it up and still not locking !!
Running out of new stuff to try except all resistors and ceramic caps plus the pair of tuning diodes discussed earlier.
Could it be that last IC that I am waiting for?
Or could it be both PLL chips are DOA?
I just ordered yet another PLL but maybe it is not actually the same type?
I remember comparing datasheets between the original DS8907N vs DS8907J and finding them the same,but maybe I missed something here?
There is another company that sells the "N" type but minimal order is 2 pcs @ $112.00 each...they can keep them for that money.
I bought another one like this instead thinking whatever ruined the first did the same to the new before going through all the components.

Oddly,with all IC chips removed I am to tune for 100mhz,then insert all IC`s in sockets.What it is doing now is showing up on the frequency I have the DIP switches set to...weird because when I touch the finals,it drifts off freq.
Something is whacky...maybe me
