Mikes kit makes getting the caps easy.
the one for the 142GTL/ washington is the one you want.
if you go through mouser, nichicon is a good brand.
as for the 8719, i can't remember which chinese seller i bought a bunch from as it was years ago, but i would imagine the ones who sell a lot of them are good.
just takes a long time to get to you.
no programming needed.
just to ease the possible confusion, pins 1-9 are toward the back of the radio, and pins 10-18 are toward the front.
pin 6 has a direct track from the VCO coil L13 which will help you confirm which pin is pin 1.
have you tried adjusting L13 with a DC volt meter on TP9 yet?
after re-connecting pin 10 of the PLL that is.
get some solder wick AKA desoldering braid, as it will make removing the PLL or any other chip much easier than trying to do it with a bulb sucker.
you might also have brown goop disease, as this radio is very old and that stuff could have eaten away at some of the pins on the PLL, the 10.240 crystal, or the VCO chip.
they tend to put it right in that area.
do you see some dark brown glue type stuff around that area?
you can make an RF probe very cheaply that will help you peak those coils that are calling for an RF VTVM.
just google it and you'll find many examples. a diode, a few resistors and caps and you just connect it to your voltmeter.
the numbers wont mean anything, but you can peak things for maximum.
An analog voltmeter is easier to read when doing this, but digital will work as well.
the reason they call for a Vacuum Tube Volt Meter in the service manual is because the input impedance on voltmeters used to be too low and would load down the circuit.
nowadays we just use a scope for those types of things.
if you really want to learn all about this stuff, get a copy of Understanding and Repairing CB radios by Lou Franklin.
it can be expensive but totally worth its weight in gold.
not only will it teach you all about setting up a repair bench, it has actual troubleshooting guides for the MB8719 PLL radios.
I re-read my copy so much the covers fell off LOL.
