Galaxy 2517 biasing adjustments are dead

18.9k ohms to ground from pad

I have to say thank you also for sticking with me, I like to work on radios just hate asking for help.. this repair is probably a little over my head but I’m Sure going to give it my all

 

[Justwantdahifiaudio]

I got the radio with no finals they were in a bag so this is maybe a possibility I see the extra pad with the no banded side of the diode going to the pad that runs to the biasing vr

 

[Justwantdahifiaudio]

I think you might be right about the caps being short on each pad???

Well, can you post a photo of what you're up against?

The foil side would help.

Ok here you go pic of the finals, and the ground strap to the cap where my pointer is 6.59k Ohm

Not here to pick apart your work, just trying to help - I have a question or two...

Note Circled areas, Blue ??? and Yellow Arrow...

Ok, the "bias diode" solders across BASE foil pad right next to the "amber" to ground (Banded end would be oriented towards bottom of photo)
A jumper goes from Bias "Amber" pad to BASE for BIAS - but 22 ohm resistor is on the AMBER pad side soldered across to ground on it's other lead.

So, I see ...

Coloring Legend
BLUE = BASE
CYAN = Collector
GREEN = Foil and Emitter
AMBER = BASE BIAS NETWORK
Light BLUE = AM Regulator
ORANGE = 8 VOLT TX​

I just see some stuff not sure if they are "oils" from flux or are they soldering issues...?

Hope the above side to side helps you...

Where your "tip" is, is an RF bypass cap - so to see 6.9K is about normal - the thing keeps RF to where is needs to belong - and DC ground and any voltages OFF of the back panel

Let’s try this again cleaned the board and my phone

The finals are used from a few 148s had 2312 so don’t mind the poop on the transistors

 

[Justwantdahifiaudio]

Diodes are in right direction

Ok, looks a bit better - but I'm still wondering the loss of voltage - and you did say the pots were ok...?

I see you have them back in..

I guess - carefully - reapply power...
