How hot or warm should the T7222 chip get. The aluminum chassis is pretty warm, but when I touched the chip plate it was hot enough to burn my finger. It's not discolored like the 3756. Takes about 15-20 minutes to get this hot. I just picked it up today. 1983 Taiwan, hasn't been used in 8 years, meter stuck, unlocked clarifier( D75,R44 and orange wire to reg) I changed back to original. TR 26 was removed and I'm putting that back in next. I replaced the cut R112. All other solders appear untouched. Does 9w pep 3.5 avg. bias is set real low on both driver and final. I see both the 27 & 54 traps were backed all the way out. I unfortunately don't have a way to measure the 54 MHz level. I'm hoping the heat is normal or maybe its just a 10v cap, there's a lot in this one.
