Have never heard of TP16.
Here is the Service Manual for the Realistic TRC-450, which uses the same Uniden PC-385 board as the Uniden Washington with the MB 8719 PLL and Cobra 142 GTL.

I just printed out the board layout and alignment point pages and seem to match my radio exactly. I think the SM I have is not right. Can't wait to print out the rest of this SM and go thru the alignment again.Hi Robb
Thanks for the link to the trc450, I think that is going to help me, I'll keep you posted.
