Thanks very much for posting your video. I had a loose tube socket in my Cary 572Mk2SE amplifier and your general approach to repair worked perfectly for me !
WOW I bought and was getting ready to replace the 4 12ax7 tube sockets on my amp. They would make noise like crazy when I touched them.Before tackling that job on a Cary V12R amp, I did what you said in the video. It is now PERFECT ! ! ! THANKS SO MUCH FOR THIS VIDEO ! ! !
Depends on the circuitry, it’s possible some contacts might have energy at some points, the safer way is use multimeter and measure all contacts voltage before using the method
@@stanzkam1 Thank you so much sir, my right socket 12au7 is loose but it works perfectly fine, I wonder if it is making full contact. I need to learn how to safely discharge the caps first, I got the tools already
I personally would be weary of it. Simply get a large-ish resistor of some value (like 100k+) and solder it to a jacketed wire. Use that wire/resistor combo to do the discharging. Touch one side from the anode of the capacitor … and then the other side to chassis ground. Should take a few seconds to drain. Be sure to test voltage after the fact.

you're the best
You are clever!
Besides doing this with amp disconnected from AC, is there any danger if you tight em 1 by 1 without discharging internal caps? Thanks mate

These chinese noval sockets are the worst crap ever made............change them for better quality.........
Sockets used in this unit are the best socket I found in market, customized PTFE CNC milling base, and high purity copper pins.
