So I measured it today and I found that the voltage on the zener is 1.6 volts dc. The other way it shows 0 volts. I got busy and I wasn't able to do any other measurements. I'm hoping tomorrow to do more measurements. I don't understand this thing. I'll talk to y'all tomorrow. I'm soooo grateful for y'all's help. I haven't said that yet but I am.

Lol. I'm sorry!    :-D

Dang you said the voltage on the zener. I forgot to measure that. I'll do that tomorrow too.

I haven't had the amp on long enough to check the op amps to see if they're getting hot. I've been concerned about that resistor smoking. Lol. Btw, I changed that resistor to a 3.2 k ohms 3 watt but it did the same thing but more so I think. So I'm gonna change it back to the 300 ohm resistor. I was following the advice of one of the older techs at work.

I hope y'all had a nice weekend. I didn't think to check the voltage on the 24 volt rail I can do that tomorrow. I checked the voltage on the resistor and it says 40 volts dc.

The only thing is, it's cooking with the 3 watt resistor I replaced it with. So my guess is that the wattage is above 3 watts as it stands.

Sorry for the mix up. Lol.

Yeah yeah. That's it. That's exactly right. I screwed up listing the part numbers. Lol. I'll check the voltage and get back with you.

I believe that zener is a 1N4752. And yes it was the original 1w  resistor. I replaced it with a 3w 300 ohm resistor. I'm slightly colorblind. I couldn't tell what the 2nd band was.  :-(  That's why I've been concerned about that resistor. The power supply to me looks like it splits in front of the filter capacitors. Then one side I guess runs the output the other half runs everything else. But if that were true it would have a negative side because of the ground reference. That's just speculation on my part though. According to my research that zener diode is a 33 volt one. There's 2 7832 regulators and 1 7831. I was thinking about what could cause that resistor to heat up so the only thing I could figure was it was the wrong value. I'm pretty confident now it's the wrong resistor value. I wonder if it could've messed my outputs up or something. They don't seem to be they didn't smoke or anything. According to the specs they're pretty hardy.

It's an actual picture though. I can't seem too get the picture thing to work.

Well it didn't work like I thought it would.  :-(

Yeah I put it in an earlier post. Here it is. 20140606_124514[1].jpg

Did you see the pictures I posted a link to? I couldn't figure out how to post them all on here so I posted the link.

Thanks. I'm about at my wits end on this thing. Lol. Maybe this is close.

This is pretty close to mine but it's lacking information.
