Back on to the Lite build progress. Last night I decided that I was going to try and hunt and kill the persistent buzz that the amp had in the left channel. With some help from Colin and Ari we'd narrowed down the list of likely candidates to either the big choke on the top panel or the floating filaments (and perhaps their routing). I had also decided to order up one of Antek's steel transformer covers to try and limit the EMF from the power trafo. So first up was testing the choke orientation and location. By simply removing the two mounting bolts I was able to move the choke significantly further away from the output transformers and also rotate it freely. Unfortunately this had 0 affect on the noise. Next up was biasing the heaters above ground which essentially amounted to creating a voltage divider off of B+ and connecting one side of the heater wiring to this. As a part of this operation I also decided to parallel the heater secondaries to better balance the current on the low voltage windings. This will also allow me to run stupid output tubes like the 6336 and 6528. So I created the divider using a ~60k and 27k resistor to create a 50V reference point and tied one leg of the parallel secondaries to this point. Colin has further recommended that I bypass the lower resistor with a 100uf cap which I'll do some time over the next few days. Finally I rerouted the heater wiring after the bias point to run away from the CCS components and as far from the input stage as possible. I also used some of LessEMF's M

Nope, I haven't even been tempted. I'm waiting for the 16s.

Call them.

Swallow the Sun - New Moon So. Very. Good.

You're not alone, it's very good and in heavy rotation around here too.

It'll also help you tell L from R more easily too.

I was going to build a duet cable tonight anyway (seriously) so I'll be in touch.

Happy Birthday!

I'll pass along the same advice, get ready. And that is a great picture.

Rough guess, $400 or so. Hard to know since it's a custom designed trafo and uses the OCC wire option which drives the price up for sure.

Probably depends on who you know. On a serious note, shoot Ari a PM about it, I think he's built a couple.

While my pedestrian audio budget will never be able to afford any of the Dacses mentioned in that review it is shocking how similar their impressions of the Bryston are compared to what I heard in NYC at the recent meet.

This. Rocks.

No worries Stretch and thanks for the offer. Part of the appeal of the Stagg was the semi-insane ~$50 price. The cabinet is pretty well stocked right now so I should pass lest I give the missus an excuse to notice.

500 would be fine with me if someone wants to offload an extra.

Both appear to be gone, showing ships in "Discontinued" where before it said 3 to 5 days. Saw this while cooking lunch, should have stopped to grab one of the 640GB drives. Frack.

I'm jealous Naaman, I stopped by my local store Friday only to be told that the Stagg they had on hand was a special order and already spoken for.

Happy Birthday Mark!

but your amp has two toooobs?

There are no current plans to build the amp that I'm building in the commercial realm but just because it isn't a 1:1 translation doesn't mean it's open source. That said, some of the information contained on the schematic may be viewed as proprietary or at the very least not something Pete feels like giving away. I honestly didn't ask because it's his choice and one I'll certainly abide by as I'm sure everyone else here would if placed in the same position.
