John Bonham : He barely touched the PTC with that plastic stick, and it moved about 3 mm, and on the back side of the circuit board, its solder is duller than the other solder points, and I think you can almost see a hairline crack... Nice vid as usual.
Bartek Bąk : I had similiar problem when repairing amplifier, it would randomly oscillate. I've found suspected section where the oscilations were created but couldn't find anything because it was super random. So i grabbed hot air gun with smallest nozzle and heated elements in that section one by one. Finally I found resistor that was being like 2-3Meg and other time 200k depending of the moon phase or idk but when it was heated a lot it always came back to spec and oscillations dissapeared. Maybe thermall stress when you were resoldering components fixed it enough to work reliable. Try out upside down compressed spray in the primary section. Thermal shock could once again cause failure.
mikeselectricstuff : So annoying when things fix themselves - happens to me all the time!
μBrainiac : I really like these videos! I repaired a pre-amp, about a month ago, that had 2 bad, hidden pads. Which made for two bad solder joints (couldn't see them in visual inspection under the microscope). It would work for any amount of time, could be 2 minutes or 2 hours, then the sound would cut out. But at least, I was able to find them both, as the sound would cut out as I would touch the parts lead with the scope probe. I hope your Combiscope's going to stay fixed, but I have a feeling this is just temporary. In my telecom days, every units that behaved like that would fail in the environmental chamber.
Don Reid : The primary switching may have slowed down because the secondary side was no longer drawing much current. It could still have been a secondary side issue or even a shutdown because of some other circuit decided there was a problem.
Starting from where you are - PC114- early days
Time for a new round of '97! :) This resumes where I left off on last early days round...

honeyphan2 : Oh, yes. I saw it online from the beginning to the end. :) I really liked Theresa/Ethan, and all the zany things she did to get closer to him. lol Also liked the whole Miguel/Charity/Kay triangle- that was crazy fun. :)
Adolfin is typing : I never cared for early PC..i should try watching it but I really loved the supernatural arcs ..same with passions..don't know if you ever seen it?
honeyphan : Well, I've never seen any of that yet -lol- I'm watching first time as I post them. But yeah, I plan to post all the early years too.
Caciona Bernstrom : I love Lucy and kevin. Fave soap couple ever. But WHO was dressing Lynn on PC. She has some really bad outfits and hair along the way.
LBF522 : Loved Eve also.
