Yet one more proximity rumination

[pjd3]

Hello,

Hopefully this will be the last thing to worry needlessly about but, would like to hear what you have to say about it.

Upon finally loading the rear panel with power switches, trickle switch, fuse holder, and output speaker jacks, it was found that one of the power tube socket solder lugs comes unexpectedly close to the speaker output jack - within an inch or so depending on rotational position of either or both.

If I face the power tube grid lug towards the circuit board it puts lug 3 (plate) and lug 4 (screen) withing 1/2" from the output jack positive spring tab. So what I'm envisioning is very large voltage swings taking place a bit close to the positive connections of the lower speaker jack. Now the good side is that this close proximity jack is just one of two jacks that will be in parallel with a higher located jack, both for the 8 ohm tap (incase of extension cab option). I can for-go this jack if a problem The higher topmost speaker jacks will manage to stay say, an inch to an inch and a half away from any power tube lugs - and you can increase that with rotational positioning.

Do you see any issues with any of this?

Thank you,
PJD3

I anticipate no problem.

+1 for no issues. Just use star washers so nothing rattles loose and make sure there is clearance when the tip is bent when inserting the plug. Add a bit of heat shrink if it makes you feel more comfortable, or switch from an open frame to a cliff style jack.

Thank you guys,

I am using isolated output jacks and will heat shrink any lugs that could rotate into risky areas.

Thank you,
