Those are pretty decent sized, aren't they? I've got some sitting in wait for my Darling amp. I've heard a few tube amps with them and they do sound nice. The Russian PIO are nice as well.

I think someone should use some motor run caps in the PS. Now some of those are HUGE. Come to think of it I've got some...hmmmm

Cheers! All I had to do was drill holes, naamanf did the rest.

Caps sound awesome, an absolute pain to install but I think it was worth it

Since I have the recommended hammond case, I will take some sandpaper and carefully remove the black anodized film where the Alps pot makes contact with the faceplate. I don't know though, maybe I will be better off with a wire connected to the case.

Hello do we (or did we) have a group buy of this PCB? It looks really interesting.

 

[amphead]

Welcome Superpong! You are about 6 weeks too late, but boards may become available. You will have to check with TomB. Sorry for your wallet.

No.

The pad is there next to the pot for the ground wire. There should be no need to purposefully ground the case. In fact, the case/ground is isolated from the power supply (AC). We only made reference to the case in case of happenstance. It is only important that the pot is grounded to the signal ground (DC negative) on the board. That's the purpose of the pad.

Solder a wire to the pad and tie the end of the lead to the screw on the Alps pot. The Alps pot screws go all the way the length of the pot and are visible on the front of the pot. So, when you unscrew them, there's gracious plenty room to wrap the wire around and screw it all back in.

Yes - one of the biggest Group Buys (biggest?) ever made for a DIY headphone amp. Check the stats in my signature below.

Actually, it's still Cetoole (Colin) that has the boards. He is still too busy to answer my e-mails, either - so don't send him any. He always gets back to us when he can.

It's a fact that he has ~50 extra boards. He may still be working with some people who've been shorted or had shipping errors. He can't hang on to that many boards, so he will sell them at some point. Also, we have talked many times about having another Group Buy around Christmas, perhaps. So, please stay tuned ...

My 2 boards are framed and hanging on the wall

Nope - That's what makes the Millett so great: 24-27VDC max.

You don't say.

Just wait until I post pics of my board, it definitely looks interesting.

I just got my K701s plugged into the MAX............THANKS EVERYONE!

Hey! This is news, I hope. Several of us can confirm the MAX does great with the HD580 and HD600. May we now state that the K701's sound great with the MAX??

 

[babbkutz@comcast]

into k701s and my initial impression is WOW! (it's still not cased) Yeah they definitely work!

 

[daggerlee]

I went away for a few months on vacation and wow this thread has gotten large. I assume there have been a few more people who have built both MOSFETs and DBs, can any of them weigh in on the comparison?

 

[babbkutz@comcast]

the range is large.......what do you guys suggest? I'm running 12AE6As at 13.5 right now.......71mV bias.......
