No, this will be my first Millett.

Yeah they're really expensive but for the ultimate in detail they can't be beat

A single Black Gate for the price of the whole ES/VitQ setup really is just a bit too nutty for me. This project is intended to be my cheap intro to tubes.

Here is the current plan for my beezer order before I go to mouser or digikey. I'm waiting on that last item to make my order. I tried to pick out enough to make a balanced and a single ended Millett Max

Wow a balanced millet, i can't wait to see that! Id love to make one!!!! I was talking to TomB about it yesterday. If i could id like to make b22 balanced amp or a millet balanced amp.

Please post up a few pics when you get cracking. Good luck!

Another way to make your wallet scream would be to get some HD600s to listen to your max. Highly recommended.

And buy a cardas cable to go with them like i just did. I bought the millet max then realised my 595's weren't as good so i bought some 600's then thought, hey why not try the decent cable too. A few hundred pounds later i have a set up i really like!!! Next i want a balanced amp. It never stops!

The listed part is obsolete(?) and no longer sold by Digikey.

Yes. The 1N4002 is a generic diode. Pretty much anything that has that number will work. Unfortunately, that also means it's treated as a commodity. So, it's difficult to maintain consistent part numbers in the BOM as DigiKey and others buy in huge lots from all over the world.

I'll try to get the 0.18 96P-series VitQ's on the store site tonight.

S**T, I have just noticed my millet has some wiring that is wrong somewhere in the amp. the sound from the left and right channels are the wrong way round. I purposely put on a song i know starts in the left channel, on my solo and x can it plays in the left on my millet its the right!

I didn't make the amp so where would i start in trying to figure out which is wrong? Could i just swap the rca's over or is it bit more seriuos?

Here is the BoM for the balanced and single ended millett for mouser: (main differences being 3x everything except only two panel LED and switches, well 400 of the small transistors for matching, the XLR female jacks (2 normal, 2 1/4th combo)). Thought this might help those who might want to also try building a boutique balanced.

Notice CA2, CA7, CA8, CA9, and RB14 are not included as they are ordered from beezar as boutique components.

I'm no tech-know-how guy on this, but it could be something as simple as a miswiring of the RCA or jack.

Yeh thats what i thought/hoping! I haven't taken it apart yet to have a look, bts getting late here. I just wondered where would be the best places to look. I guess is should try headphone jack and rca's first?

 

[el_matt0]

howabout this. i bet a more likely scenario is that you potentially just have the detachable cable of your senn hd600s reversed..? try with different cans to confirm its the amp first. If not, then yes it is simply either the RCA inputs wired in reverse, or the L and R channels to the 1/4 output that are flipped (both a 2 second fixer upper, but a silly mistake by the builder nonetheless).

If the pot and headphone jack arent airwired, then the inputs are pretty much the only place that can be wrong. Could also be the headphones as el_matt0 suggests.

 

[el_matt0]

oh yea forgot most people dont even airwire the pot, that narrows things down substantially as mr.majestic correctly points out. should be a simple problem to solve by all means - although my moneys still on the senns to be honest.

Another MAX lives!

I've only had it running for about half an hour... Its improving constantly. Its still caseless and connected temporarily.

Thanks for everyone's help! I've been very impressed with the level of support available on this DIY amp.

Pics at the weekend when I've had chance to neaten it up!

Well I've placed an order at Beezar for 12FK6 tubes, ES and VitQ caps, spare transistors, spare sockets, jacks and TO-200 mount kits. I'm fleshing out the final details of my kit with Jeff, namely adding some extra 1000µF caps.

I'm excited.... but the G/F is going to be p%&#ed!
