Wow. That worked. Like, really worked. Two Nichicon 220uF caps (I used axial vs radial)
- and now, ALL hum on ANY 68FG or 6SN7 is GONE from my 336se.
The only things I really have to ask are
1) Is this going to cause the amp to become less reliable down the line?
2) In other words -- why in the WORLD isn't this done at the factory? I can't see it being a cost saving issue. There must be a reason??
Anyways, so that folks may be assisted in doing this in the future, here are pics of my mod...
The electrical tape, don't mind it, just burnt the insulation there a bit while soldering so a slight precaution...
I tried to get some angles that show the connections well. This along with the previous images in this thread hopefully will be a help to people.
