You know us, little bit of raping and pillaging never hurt nobody so no promises...

This was going on long before that. These new fangled electronix are considered luxury goods up here so they should be taxed accordingly... Speaking of the bailout though, I have to remeber to vote tomorrow. It will be fun take part in something that will truly piss off the EU. Woot!!! I damaged a few units while trying to get the front row to make contact with the board. Could be that I used an axe to do this...

When fitting the 3381's, buy a 0.7mm drill and enlarge the holes a bit. Otherwise it is very fiddly to get them to sit correctly...

Shielding an R-core seems a bit unnecessary to me...

Serviced my dads drill press. Replaced the belt and aligned/lubricated all moving parts so it should be great for the next 30 years.

A BH isn't that expensive to DIY...

Now try an amp with a CCS loaded output stage... The biggest improvement is indeed with drums and the like where the abundant current delivery really comes into its own.

Too bad they use the older Stax sockets which were fixed with epoxy. Was there ever any doubt that I've owned a few of these...

They smell good too. Right now I'm listening to Iron Maiden - Powerslave. All tube amplification FTMFW!!!

Extra resistors and the cap would surely help so it is worth a shot. You could also just copy what Koss did to the letter and see what happens.

You can also just upload the pictures to the site here. Just click the "insert picture" button but they have to be jpg, png or gif. It's been a while since I looked at the exstata bias supply but adding another cap or two at the output could perhaps give you the filtering needed.

What you need is something like the SRE-B3. It would be easy enough to fabricate though...

The 5M resistor would go in line with the bias making the ballast a total of 10M. What did Kevin tell you to do with the KGSS bias supply to increase the filtering? A cap to ground after the ballast resistor is what Stax did prior to the SR-Omega project so something similar to that could work.

Don't remind me... Still they can't do anything better then either a Mk1 or the SR-O so they aren't really needed for day to day listening. Plus the Mk2/A parts take care of the minor comfort issues I had with the Mk1. I do want one though.

This wouldn't be a fair comparison since the HE90 output runs at a lower bias (500V) and has a higher value ballast resistor compared to the Stax output.

Happy Birthday Nate!!

The new ones certainly do. I only use a cheap Tag though, my brother got the watch bug... Edit: Should say that I'm not talking about the noise in the gears but rather the wristband rattling

Since I've never heard the squealing noise it's hard to know what's going on but the phones having a physical shock causing the squeal could point to dust issues. The dust covers on the ESP950 are suspect so it ic certainly a possibility in combination of the lack of an output capacitor on the KG bias supplies.

I usually call them Rattle-X (way funnier in Icelandic though)

Team Tag does indeed approve!

Great work there Colin. I've had to do this a few too many times and I get angrier at Stax each time. I've seen this on pretty much any amp built after 2000 so there are a lot of 100V amps which are a pain to convert but not all.

The non SE version certainly did but those output tubes look like 6H30's so probably less heat involved Very much Krell KCT...

Good luck Nate.

Stax probably have a few T2's still in use and given how similar it is to the basic BH design, they sure know how the phones sound when properly driven. I do think that a redesigned 007t with ECC99's and a simple CCS would put the Stax amps back in the running, especially if the Yen finally drops a bit in value.

I'd say 36.345%, with a margin of error of 0.003%... For me the music just snaps into focus with more power. The imaging is more precise, bass is more linear, treble extends further etc.
