n_maher Posted May 6, 2008 Author Report Share Posted May 6, 2008 It appears that the tubes and transformers are located not by looks but by where they would sound and perform best located.I believe that the layout is very much function over form. I don't know that he made every decision that way but it's easy to see the power and signal flow diagram just from the top panel. I bet it's heavy, those trannies look menacing. IIRC it's a 40 something pound beast. I'll try and get an internal picture or two from Pete if I can. Quote Link to comment Share on other sites More sharing options...

recstar24 Posted May 7, 2008 Report Share Posted May 7, 2008 Did anyone give this amp some grado love? Biggie. I think I read some impressions with balanced RS-1's and balanced PS-1's. I believe they were both thumbs up. Quote Link to comment Share on other sites More sharing options...
Voltron Posted May 7, 2008 Report Share Posted May 7, 2008 Did anyone give this amp some grado love? Biggie. I think I read some impressions with balanced RS-1's and balanced PS-1's. I believe they were both thumbs up. I had both balanced brown leather RS-1s with a 4-pin XLR and balanced PS-1 with Equinox 2x3-pin XLRs that made the rounds a bit and sat in front of my monster Rockhopper balanced B22. I was very pleased how they sounded from my amp, and I also heard my PS-1s and Craig's RS-1s from the EC Balancing Act. Craig's amps do great things for Grados in general, but the PS-1s sounded a little bloated from the EC/BA on the first track I heard them on. Good but not perfect. Then daveDerek put on a Linda Rondstadt with Nelson Riddles Orch disc and Craig, DD and I all thought it was amazingly perfect. The RS-1s were outstanding from the EC/BA and the TTVJ 307A also. Trying to remember what I heard on the Menace and grawk's mosfet amp but it seems like they were s/e Grados. Woody HF-1s? Anyway, both sounded great but my tube bent made me prefer the Menace and the immense power it threw into the drivers. Sweet. Quote Link to comment Share on other sites More sharing options...
n_maher Posted May 7, 2008 Author Report Share Posted May 7, 2008 Did anyone give this amp some grado love? Biggie. Yes, I did - my balanced HF-1s. It drove them very, very well on the low-Z balanced setting. Quote Link to comment Share on other sites More sharing options...

I walked away after going to this thread and then saw ryan's post about impressions with balanced Grados and I forgot the thread was about the TTVJ 307A. It really handled the Grados well, and I am honestly trying to remember whether I brought the PS-1s over there or not. Scattered at teh meet too, don't you know.

Iron_Dreamer Posted May 8, 2008 Report Share Posted May 8, 2008 The 307A sounded excellent to me, driving both the RS1 and K1000 with plenty of guts to spare. I'd probably stick with an uber-B22 for the simplicity factor, but if I wanted one of the best headphone amps out there, and it had to be a tube amp, this new Millet would be one of the first to be considered.

4N6 Posted May 15, 2008 Report Share Posted May 15, 2008 I just talked to Todd about this amp and I am getting jazzed. The selection of tubes was very smart and it looks to be able to drive any set of headphones this side of electrostatics. Best of all, from what Todd told me, the wait for one of these amps to be made is only a month. Just a smidgen better than HeadAmp and SinglePower. Now figuring out how to afford this beast!!!

aardvark baguette Posted May 15, 2008 Report Share Posted May 15, 2008 Tube question: Supposing one had to replace tubes down the line; are these special, in their use of the wire going to the top? Or do you re-use the same wire? I've not seen this in any other amp before, so I apologize for any gross incompetence here Quote Link to comment Share on other sites More sharing options...

Or do you re-use the same wire? I've not seen this in any other amp before, so I apologize for any gross incompetence here The 307A has a metal nub at the top like this thing which serves as an electrical contact. You take one of these doohickies, solder a wire onto it and clip it to the nub thingy on the tube. The wire & clip thingy stay with the amp, you don't change them, only the tube gets changed.

aardvark baguette Posted May 15, 2008 Report Share Posted May 15, 2008 Thanks for the explanations guys. I'm really starting to lust after this thing.

It is absolutely lust-worthy. It is an all-rounder that can really drive an amazing array of cans beautifully. DEW EET!!! As a bonus, it's hand made by the man himself, pete millett. The other TTVJ/Millett offerings are being built by Todd, who was a solder tech at a high end and/or military electronics job before HeadRoom and TTVJ. Maybe these are different. Did Pete or Todd tell you that Pete was making these monsters himself? Quote Link to comment Share on other sites More sharing options...

I'm pretty certain that Pete at some point mentioned that he was building them by hand. I wish I spent more time with it but time was something I didn't have a lot of. The little time I did spend with it was pretty damn enjoyable. Quote Link to comment Share on other sites More sharing options...
deepak Posted May 15, 2008 Report Share Posted May 15, 2008 So is there any chance PM will design an electrostat amp Quote Link to comment Share on other sites More sharing options...
n_maher Posted May 16, 2008 Author Report Share Posted May 16, 2008 So is there any chance PM will design an electrostat amp Highly unlikely. Knowing how some of you feel about this I approached the idea with Pete during the meet. He said it was unlikely for a multitude of reasons but the first two that came to mind were that a) he's not a big fan of stats and that it would take a lot of time and engineering to do it right. Considering that when he does DIY projects he flat out refuses any sort of compensation I can understand why he wouldn't take on something that isn't particularly interesting to him and that would probably cost a fair amount of money and time.
