Today I got some final (I hope) work done. I know there are some that absolutley blast me because ... "WHY don't you just recap everything and it will work fine" folks. Uhmmmm... follow me and you will see just WHY. So, today I 'finished' the power supply, neated it up, added a CL90 (probably too big). I moved the heater wire to the other side of the CL so it would be softened on start up.
Next, I finished the recap on the audio section. Replaced the coupler, decoupling cap and another. Done.
I powered up to check things and this was the result:
I discovered a hum bar going up the screen and after some checks (think) found it was coming from the inrush current limiter, so I bypassed. Set works great for about 5 minutes then the HV drops off and pic goes to crap. So, next step - replace the cap inside the HV box that I suspect. That means pulling the big tube. It's ok, I want to clean things and test the tubes.
Before:
Tharez that lousy cap that is probably killing my HV.
