Amazing...emailed the Panaxis people and to my surprise,said he had just ONE original DS8907N PLL chip left from this kit.
Of course I bought it !!
When it arrived,plopped it in carefully,powered up and NOPE...still same thing...no locking.
Not being a professional having all the fancy test gear,it is much easier for me to just pull components and replace.
So far...replaced a bunch,cleaned and tested all there is on this thing.
Now...going to pull some common diodes and a 3904 transistor and just replace those too.
Soon,will be replacing all ceramic caps and chokes if I have to.
Pure insanity...but now a quest.

im sure i shouldnt have to say this, but keep all of the old parts that you have replaced in case you need them in the future  :)

All old parts saved...gonna set this aside for now as I have other priorities to finish up with.
Sometimes working on something too long makes it worse.
I removed the DIP switch and realized I had not replaced it but only removed, cleaned and tested.
No change.
Going to walk away from it awhile.
