This amp had prior work (pooly) done on it and I don't trust what I see. Can someone help identify/confirm them for me from the following pictures?
First pic is part of the right channel. Showing in front of Q215 somebody let the smoke out.
Second pic is part of the left channel. Showing behind Q115 from left to right, 47 Ohm resistor, 68 Ohm resistor, 6V Zener, and a 475 Ohm resistor.
Are those correct for both areas shown?
Third pic shows two resistors circled in red. The one on the left looks original but is burned. The one on the right looks replaced and is 150 Ohms. Is 150 Ohms correct for both spots?

I'll be glad to look all those up for you but I have a appointment I have to run to tonight shortly. So if tomorrow is soon enough I'll get back with you on the info you want....C🙂
Once you remove the bad resistors in the right channel you will see the following board locations. Heres what goes in thoose locations
R239:47 ohm 1/8 watt resistor 5% tolorance
R238:68 ohm 1/8watt resistor 5% tolorance
D1:1N5233B diode
R244:475 OHM 1/8 watt resistor 5% tolorance
Left channel resistors appear to be right in your pic.
R233: 150 ohm 1/8 watt resistor 5% tolorance
R218:51.2 ohm 1/8 watt resistor 5% tolorance.
R133: 150 ohm 1/8 watt resistor 5% tolorance
The resistors circled in red in your pic are locations R133,R233 yes they are both 150 ohm
R239:47 ohm 1/8 watt resistor 5% tolorance

These are great amps. Hope you get her straightened out. The first time I worked on one it was a painful but valuable lesson. Slightly more complex than your average repair of the output section in my case. Got it figured out with the help of 1moreamp and my buddy has been running her strong for over 2 years.
Awhile back I worked on an XS4600 that was actually an easy repair since nobody had been in it before and it wasn't rode so hard. A luxury I guess.
This amp on the other hand is a disaster. It wasn't worked on with skills to brag about, which is why I distrusted the areas above. I'll be keeping the defibrillator at the ready.
