I'd like to go ahead with this if you have room.

Yup, I'll include you on the list.

Is there an upper limit on cap size (uf) as I have some Erso caps that are actually rather good. Also, what voltage do these need to be? The ones I have are 250V IIRC.

You can probably use whatever you want in terms of size. There can be an issue with a large cap charging across a parafeed transformer and magnetizing the core, but probably not an issue here.

I have been curious about the parafeed amps for a while but honestly cannot commit to building anything before August so I will most likely have to sit this round out unless you end up delaying the process a little. Looks very cool ..dB

Most definitely in on this.

No skill with tools here. Good luck with the project.

I'm in on this if there are any left.

Don't have a tube system for the 3rd bathroom yet...

Surely something other than a new amp is needed......

I'm not sure if this would be okay or not, but I would be interested in sponsoring some DIY skills. Would any DIYers be interested in building one for me? I will of course pay for all parts and labor.

man, this must be the most amazing, bestest sounding amplifier evar!

You guys are too funny. Actually, it's all the LED's that are the most dazzling.

I figured that switch on the front was the "ortho" switch

I'm serious... The singlepower extreme with ipod is in the master bathroom. With the

large soaking tub its a great place to listen to music. (shades of billy)

then it must be destiny ..dB

You got the last one ... I thought you hated output transformers?

I'm willing to expand my horizions...

Besides which i have more than 8 tube Mcintosh amplifiers... Too bad no one makes transformers like

that anymore. And a classic original Marantz around somewhere... Plus the two short wave radios

(they probably don't count...)

Better than running 200 volt black gate power tank capacitors at 350+ volts...

Should not be very hard to assemble, I think i can manage.

It is a crying shame that Black Gate is now defunct. The guy who ran the company in Japan has been trying to limp production on with Rubicon, but they pulled the plug a year or more ago.

Guys -- sorry for the long delay. We have the cases. We are just waiting on the transformers which have been promised and delayed a number of times. They are winding them as I type this, so they say, and should ship to me early next week.

Also, one person backed out so if anyone wants to jump in for the last one send me a PM.

Cool Doug, looking forward to it. We'll see if I attack the case with the mill.

Guys -- sorry for the long delay.

Well, the initial 3 to 4 week estimate for winding the transformers turned into 2 months. They finally arrived last week, and the pinout was wrong.

New ones are being wound, and should ship soon ... I hope. They told me it would be this week. We'll let you know. Sorry again for the delay.

I sooooooooo want to, but simply cannot afford it right now

I want as well but can't build anything to save my life

I had an opportunity to listen to this amp at the recent Atlanta meet. It was brought by Tom B. and I was very favorably impressed by how well it sonded, I also like the form factor.

Colour me a little curious to how this project is coming along. My soldering iron is getting tarnished and needs something to do, and I have a little spare cash in the kitty. Also, just wondering whether the RK27 is going to be the only on-board pot choice...... any chance that the pads for a DACT CT-2 could be added as well?

Thanks lads!

I think it's pretty much ready to go, Tom just had too much to do prior to CanJam to get the parts kitted. I'd expect things to move along pretty soon but we didn't talk dates. Also, based on what I saw for space constraints you'd have a hard time using a pot that was any larger than the RK27.

Thanks!

Now that CJ is over, this is pretty much top priority for us. Tom is in possession of PCBs, transformers, cases, tubes, and a few other parts, so it is really a matter of when he has some time to get everything together. Should not be too long, though.

The target price for the kit is in the $300 range. That may go up or down a bit depending on how much parts cost us, but we are trying to keep it around there. It doesn't make sense to use a pot that costs 2/3 of the rest of the amp. And it's too big. And, I don't think it makes that much, if any, difference. If you really want an upgrade, I can supply you with some Electra-Print nickel core OPTs which will make a ton more of a difference. Or with one of these: http://assets.head-fi.org/6/6d/6ddc8d48_IMG_0688.JPG I hear they are nice.

Anyway, I think the Noble pots have the same footprint.

Sweet. Looking forward to the big unveiling

Got to listen to this briefly at CanJam and liked what I heard with the HF-2's. Looking forward to the release of this.
