Here ya go.

Yep they changed a few things around on this unit. If you noticed they ran another jumper back there from one gate to the other gate allowing one trimmer to control the voltage on both finals. These seem to be some good working radios. Take notes and pictures of that back panel. I have copied...

VR11 sets the driver voltage and VR10 sets the voltage for both the finals.

If it was the one on the foil side of the board then C44 is the one.

Sounds like you bought a cheap speaker. Is it a squeal or a squall ? If squall then there is a grounding issue. Squeal is feedback from a low ohm speaker or a bad speaker.

If you are using Google then go to settings then Safety check

The 15 volts is what has had me scratching my head from the get go. Was wondering when someone would catch on to that.

Here is the best one yet! Full Detail on how to peek a radio!!

What power supply are you using? 14.3 volts is pretty high. Yes the side will get hot when you are TXing. That is normal. Here is a picture of where that Diode goes:

Figured it out. Check those crystals is all I can say!

Would have been nice to see the outcome of this as I have a 959 with the same problem. Both driver and final was blown. Installed new ones but still no TX power out.

RIP Mr. Tallman. Prayers sent for your family.

Wanted to share some info with everyone in case someone comes across this problem with an older style Connex or Galaxy. When you turn the radio on "Cold" and key the mic the frequency is off by 10 KHz and once the radio warms up it will go back on normal frequency. Check X2 Crystal 14.010...

They guy will sell it for $200.00 if anyone is looking.
