They did fix them. This has been confirmed, both why and how they did it.

Found it:

It is but I've seen somebody turn basic Ikea wooden boxes into speakers. It was at the Euro triode festival.

Ahemmmm... As it happens I just got some new punches in from the UK today. Douglas helped me out as RS were being dicks...

Not sure when it was implemented and Stax aren't saying, the whole mantra that they will continue to improve (or fuck up) the product holds true with them. Basically they changed the diaphragm setup so now they aren't as bright. For me they went from basically unusable to very good just because of that.

Thermal ratings on resistors are a crapshoot at best (hello Mills!!) so a 2W might work but it also might not. Try it and then measure them...

I could have put it on my website that I didn't recommend using the KGSSHV (I think that one was a HV) with the SR-009. I certainly said it enough... That was with the old ones though and it is no longer a factor with the fixed SR-009's. I never got confirmation that they fixed the 007II/A too so I just bought a set to try out. If they fixed the diaphragm then they could finally be modified like the SZ2's.

I have the S3/5SE's here and they are lovely speakers. I read at some point that they are inspired by their BBC namesakes but the cabinets turned 90° and the baffle isn't screwed in place. Also biwire from the age when that was all the rage.

Nope, no carbon files have been tested. You have been warned as that one was a rush job. Current is fixed so the voltage is the variable. I won't be going over 400V with this one, same as the Megatron.

What socket are you using? The teflon ones can be loose.

I bought two dozen as they won't sell you just a few. Took a few weeks as this is custom extruded . Price was good but the shipping was crazy expensive. Sending aluminum UPS will do that...

Hum in the earspeakers can be a connection problem at the socket. I has happened to me before.

I had Fischer make some 350*150mm sinks for me recently. I also have some Conrad from a group buy on DIYA years back. I'll have to find them and measure the exact dimensions.

The problem with the ebay ones is that they are mostly crap. I'm moving to use the old Buchanan ones now (TE) as I deplete my stocks of all the other ones. I'm not too keen to use the 6SN7 at this level even it it is a GTA/B. I ran my "Stúfur" design with GTB's at 600V in grounded cathode and it wasn't ideal. That was a cheap "volksamp" attempt so a small compromise wasn't a problem. That said I did have the SRX pcb design open yesterday so I might build some. I need to make it about half the size and have the tube sockets face the right way. I have some oddly shaped boxes which would work for this and not much else. Well that mini BH design I was kicking about would also work...

The pass amp is probably just an uprated version of the their preamps but one can hope they do something more robust. As for the Rossi crap, the actual amplifier in these is just some cheap chip amp garbage. Think RSA Darkstar but even worse.

It is a modified version of the BH power supply. Just look at the files on Kevin's site, the clue is in the file names...

I'm not selling them any more as my stocks are dwindling. I have the pcb's for the TKD/Alps RK27 too. Also some used stereo DACT's that I need to get rid of at some point.

Kevin and I have been laughing about this garbage for weeks now. His amps are up there with the biggest pieces of fail money can buy and this won't change that.

Yup, that one works.

You are joking, right? How can those mods not make the amp perform worse than a stock unit... a stock unit he thought he was paying for?

Those caps will not do anything except cause problems. The stock parts are Vishay 1841 series 0.01uf/630V. This looks to be the correct one: http://www2.mouser.com/ProductDetail/Vishay-Roederstein/MKP1841310635/?qs=sGAEpiMZZMv1cc3ydrPrF2QyZc89JbQZ9Nh3NRNrFUU%3d Could be different pin spacing but 15mm was the norm for Stax. The resistors can be swapped for any good 30K/3W unit such as this one: http://www2.mouser.com/ProductDetail/Panasonic/ERG-3SJ303V/?qs=sGAEpiMZZMtlubZbdhIBIK8nywws5AKnl6zINSxFk8g%3d The large electrolytic caps have also been replaced but you can let them be unless they are badly mounted or something like that.

I never take mine off. Gotta watch out for those sunrays....

Wow... just wow...

The REV numbers are pretty much meaningless. The true rev numbers are the file names but they also just tell a part of the story.

The fireworks are mostly a thing of the past as we've improved the circuit boards over the years. This is still a very high voltage amplifier so if the soldering isn't perfect and the circuit boards clean of any flux, it can blow up. I'll send the larger offboard PCB files to Kevin and if he's happy with them, he'll add them to the library.
