No power from the power supply

So you’ll see from the post below that I am still struggling with the mystery of the charred RCA jacks on the inside back of my  Ten- Tec Century 21. The pic above reflects some cleaning and examining I did today to try and figure out my next move.  If there is anyone out there that could compare my picture with their own unit, I would love to know if there is suppose to be any components where I have a gaping hole…

I did some DC reading from the IC1 on the power supply board and all the voltages where very low, somewhere below normal but still above the level of a “tripped” power supply.  I am not sure what all this means?  I got low readings on Q1 and Q2 as well.  Just what component is the cause I don’t know.  I do have a good book I think I’ll consult called “How to test nearly everything”, or something like that…  This will be a good lesson on how to troubleshoot.  I did buy this unit with an eye towards learning about HF rigs, after all this aged rig still is possible to troubleshoot, all of the components are through the hole.

I am also going to look into transformers, is it possible that they can go bad??  More to come…
