Nothing concrete really but one will have only two DHT's in it, rest will be transformers. Not meant to sound nice though, it's just supposed to be bonkers. Well that and very, very expensive.

Is it this one? If so I would account for a bit more room as the knob might not sit perfectly on the shaft and cause some contact issues.

I'm in Iceland so outside temps are never a problem.

This is exactly why the next "poor mans" amp will be based on tubes in regular production. It's a huge compromise but I've had it with sand EOL...

I'm working on a few Stax DHT amps but nothing as insane as Kevin's 12 tube monster. Not going to start any new projects anytime soon though, it's time to clear some of this half finished stuff.

Didn't get this from me... ecd2.pdf

It's better to match but it's not necessary.

BT is BitTorrent, i.e. how I watch US tv...

Any 130V zener will do, any wattage and tolerance will do. I should have some LSK389's but I'd have to check. Just shoot me a PM so I won't forget. Now it's time to patch up this nasty cut I got while drilling the front panel for the newest amp...

Bdent is just more expensive but the part is out of production so it's not going to get any cheaper. No sub available with the same or better specs. I can help you with 2705's as I have a bag full of them and any 130V zener will work. I got some from Mouser recently but don't remember the partnumber...

The only drawings I have are off the front panel. All the back and internal bits are done by hand.

Ditto but that might explain the very strange 3675's I have here that test like the real thing...

Makes me wonder what the Icelandic sound would be like....

Yup, I recently stocked up on them again.

It's one of the best TV anything I've ever seen so definitely worth a watch.

Yup, very much like the German auto makers. With MSB you buy used...

Get the "cheap" MSB dac for a nice compliment to the BHSE. The USB inputs are not cheap (even my dealer complains about his price) but the best I've ever tried.

No Lambda Pro is worth 700$ IMO. Odd layout with the audio transformers so close together but nothing astounding either.

There is a review of the ECD-2 in the newest Hifi News and they like it quite a bit.

Make sure you order extra long wires from them as they seem to think 10cm is plenty for all applications...

That would be possible but pots are problematic.

Relays and a stepped switch would be an easy way to adjust the gain. Now if you want it to be a volume control then you are looking at KX-R levels of complexity though...

We strive to put all traces on the back side but often it just isn't possible, hence jumpers such as that one.

Don't run the amp without those caps.

Yup, package doesn't matter. Fairchild does make a nice P-channel but I'd guess we'd need a lot of units for them to make complimentary pairs for us.
