Back to work on the HQ-129-X.
Remember the mess that was the set's electrolytic capacitors? If not, here's a reminder.
Thursday evening, I returned to the workbench and decided to prepare an old twist-lock capacitor I had found in the junkbox.
I cut off the aluminum at the bottom end and carefully disassembled the unit.
Then I installed three new Nichicon 10 uF, 500V electrolytics I had bought just for this purpose.
Soon, I had it all together again:
All restuffed, reassembled and ready to go where the original electrolytic once was mounted. The original was a four section unit, also containing a 20 uF, 25V electrolytic. Since the twist-lock electrolytic can I found only has three terminals, I will install a new 20 uF electrolytic direct between the output tube cathode and ground.
