I think that's as complete as it gets these days...

Nothing in there about 24K gold case though.

which is alot less complete than it used to be... a lot of stuff has been pulled.

one of the people who have custom ordered an amplifier should be able to tell me, there is some sort of a selection guide. I've seen snippets of it around...

Thanks though!

I think the whole concept is that the only way to get the info these days is to call. He hardly has anything anymore that qualifies as a standard amp with the exception of the Extreme. Or at least that's the way it seems to me.

Ok, probably a stupid question but without any instructions or any place to download them from could someone please tell me which position is the input tube? I'm guessing it is the rear-most position but guessing with stuff like this is beyond a bad idea. Clearly this doesn't matter if I'm using 3 6SN7s for testing purposes but considering this amp came with 5687 adapters I figured that its owner will more than likely want to know this info eventually.

Is it one of the black chassis MPX3? If so, looking at the amp from the front the input tube is the one on the left. The output tubes are the other two .

[PFKMan23]

Assuming you have a new chasis MPX3 the gain tube is the front most tube. In the toasters, it is on the right.

[n_maher]

Thanks guys, it's the newer style black chassis so that would mean the intput tube is front left with the drivers occupying the center and rear right positions, correct?

[PFKMan23]

Yup.

These adapters must be some of the earlier ones Mikhail did, they have no markings to indicate what the hell they're for. Thankfully they're all supposed to be for 5687's but that seems pretty crazy to not have them marked, doesn't it?

Even the newer ones don't have great markings, just something looking like the adapter type scraped onto the bottom.

I'd greatly prefer something to nothing! I'll probably try to mark them in some way for Mike in case he picks up other adapters. And it's official he got the deal of the century on this amp.

nate:

do you have the spec on this amp? just curious for purely reasons....

[n_maher]

All I know so far is that it has a stepper in it in place of the standard volume pot. I hope to have a go at opening it up tonight but I'll be working late so I'm not sure how much time I"ll have to play.

[luvdunhill]

finally got some pics.... now, if I can just get this thing cased up ...

[postjack]

damn you DIY folk are crazy.

[n_maher]

I found opening the case quite easy, 4 fasteners and pop, naked MPX3.

pics now.

I've asked Mike if it's cool to post pictures of his new toy, just waiting to hear back from him. I have no reason to suspect that he'll say anything other than yes, just want to make sure he's cool with it before I go showing off its guts.

[n_maher]

fine, be that way.

Dude, you want to piss off your lawyer, go for it. Me, I want to stay on his good side... Aw hell, one pic can't hurt.

[n_maher]

aw man, it's a PCB version, i was hoping to see some spaghetti

Nah, this a recent production amp, very few bare wires in here. That's a good thing for me, less chance of getting a shock. Installing the preamp outputs looks to be a pretty simple process as well.

[909]

this seems like an opportune time to post extreme guts.

just to tide us over....

[tyrion]

Nate, post away. I'm pretty excited about the amp. Sometimes it pays to be sitting around the office all day so you can catch the good deals.

[n_maher]

Ok, more pron of Mike's new amp. Definitely up for consideration for deal of the decade at least...

[hYdrociTy]

Wow that looks really clean and neat
