My K10A build

[MJL21193]

The final push...and I'm done.



A look at the power switch. Even with two high intensity LEDs, it is a cool muted glow - nothing that's going to grab your attention and hypnotize



And a last look from behind:



Over and out.

This amp looks very high tech.

Thank you housing
Nice to see someone other than me is looking at it

How's your RMI build coming along? Having fun yet?

Hi John,

Got the boards but not yet started working on it. Am still working on the Beta 24 from another forum.

BTW, how does your RMI sound?

That's a work of art, MJL.

What did you use for the illuminated switch ring? I've been thinking of the same idea on an amp I'm building, but couldn't think of a source for the plastic/perspex surround. I'm thinking of a perspex drawer handle or something similar, drilled.

I hope the child you took the Pooh book from doesn't find out!

Cheers

Stu

I tested the newer amp with a speaker and the turn on thump is nearly non-existent. I don't know why this would be, maybe a difference in tubes?

Yes, it is a difference in tubes. It all depends on how one of triode sections warms up with respect to the other. It will probably change over time as the tubes wear out too.

Cheers,
Glen

Remember, mine is NOT the RMI, mine is an Abomination!

Sounds spectacular. The best amp I've built so far.

Hi Stu,
I briefly demonstrated the construction of the switch here.
I won't lie, it's time consuming and you need to be relatively skilled to have it work out well and look good. That said, it is unique.

I won't be using this amp much, just when I force myself to do office work, so it may take a while for the tubes to wear out. It's not too big a deal, not like it will blow up the speakers. It's nice when you're showing off the "hi-end" gear and it starts silently though.

I haven't given it a proper listen yet, as I haven't even started the speakers that will be paired with this. I wanted to try a fullrange design (like the Fonken) but the fact is that I have too many drivers sitting around here unused - I'm better off to build with what I have. A pair of Vifa PL18 midwoofs and a pair of 2" cone tweeters that I'll horn load with the solid wood baffle. Not high efficiency, but the office is small and I don't need 120db!
Should be interesting.

Thanks John. Quite innovative!

John,

you don't happen to have the DK number handy, before i toss myself over the balcony ?
I gave up on finding a chassis mount 30Vac (or twin 15Vac), so anything will do.
