Power tube removal on a Switchblade

I decided to remove 2 power tubes from my Hughes and Kettner Switchblade. When doing this, you can remove the inside 2 or outside 2, but not 1+3 or 2+4. I consulted with Hughes and Kettner directly to make sure that this would work and that it's not an urban myth.

Because modifying my amp scares the hell our of me I phoned Steve at Act 1 Music in Langley. He gave me a very important reminder:

"Use half the impedance of your speaker cabinet when plugging in your amp" This is because your amp will be using half the power load.

I'm still using only 2 tubes for last year and still sounds fine. Has anyone replace the el34s for 6L6s I have some 6L6 power tubes, but dont know if I replace them it would damage my amp.

@BOBBYGITRPLYR Don't do it. It'll mess up your amp. This can be done on the switchblade TSC but not on the original.

So, do you still using only 2 power tubes?

It is still sounding great?

I think i'm gonna try it with my jcm 900.

Thanks!

@RSBband2008 It still sounds great. I've continued to keep the tubes out. No problems yet. A word of caution when pulling the tubes:Don't jiggle them or the center of the plastic will break. The tube will still work but it sucks when something breaks.

awesome man, im gonna do it. then instead of plugging my 8 ohm cab into the 8 ohm spot, i would use the 4 ohm spot correct?

[Koneesh]

@Gzegomax  yes, 4 ohm head to 8 ohm cab

[BOBBYGITRPLYR]

@Koneesh Thanks!

[RSBband2008]

@Koneesh Thanks for the advise!

Rock On!

@Gzegomax  4ohm from the head to and 8 ohm cabinet. The rule is having the cabinet number larger. Let me know how it goes.

@Gzegomax No loss in bass response at all. That being said, I've been trying to get less bass in my guitar sound to avoid a muddy band mix.
