Should I be worried?

[Goran Lorencin]

Dear tribe of PRS, I ask you, should I be worried about the KT66's kissing in my MT15? Is this a no-no because of inadequate heat dissipation or not?

Did not know they were that big!

NO NO!

 

[jxe]

no don’t worry or no don’t do it?

 

[aamefford]

I’m with NO! NO! DON’T DO IT!

1) it fails the look right test miserably
2) Hotter where they touch than the rest of the glass
3) see 1 and 2 above again.

Others will have more to say of course. I just don’t like it.

Absolutely 100% do not do it.

Check this KT66 data sheet. At the bottom of pg.4 it says the spacing (center to center) should be no less than 3.5in, and this is a ~2in diameter tube. Which means there should be ~1.5in clear between the glass, minimum. You've got zero.

Not enough clearance around the tubes means not enough heat dissipation and the temperature of the area will just increase. Fast way to kill a set of tubes and potentially damage your amp in the process.

I agree with the others who've posted.

"You're standing too close. I need my space, man."

Pro tip: put an alcohol soaked rag between the tubes to keep them from rattling.

Thx. Well ... I was afraid of that, although 9cm between centres is still very close, but not kissing like in my case. The tubes are HUGE, was not expecting that :/ ... so I already have to say goodbye to my recently acquired JJ KT66's, damn you PRS for not thinking of my needs when you were designing the amp!
KT66's anyone?

And, for such advanced anti-vibration techniques, what is your preferred alchohol?

Malibu

Malibu

Makes sense. I mean, you wouldn't wanna waste the Veuve on that

Yeah, and what else would I use Malibu for?

Paint stripper, maybe????

That would only make my paint smell like a stripper.

Umm.....not necessarily a bad thing? Cover up the smell of the cat in the basement???

That f**kin cat..

KT66's, Malibu, cats, ... some of the tough, and usually wrong, choices of the average Joe with a guitar.

DO NOT DO IT!
