  1. Tell me that's the one that Justin built and not the shitbox pabbi1 fucked up?
  2. I prefer the highly modified 007A but the difference is slight. They will how ever last much longer, no cable issues and all that. Hell no that they will be used... ever but how cool is it to have some of Single Power's finest.
  3. I was more jesting at the HF thread on the imbalance issue where nobody has the slightest clue and it has been suggested that PJ sets are somehow different... I can't help but get this slight feeling of betrayal when I look at this pile of shit and the epic work ahead of me...
  4. ...so I've had my new SR-009 for two days and I've already started to modify them. First for the good stuff, these aren't as fucking bright as all the early units I've owned/had access too. They can be a tiny bit too hot at times but this a marked difference to the earlier sets. This also means the odd reverberation with voices is also mostly gone. The bad news is though that the bass has a large gap in the FR simply missing and the imaging is far from good. Coming off a steady diet of SR-Omega and modified SR-007 SZ2 these two factors are all too apparent. There is a strong center image but it lacks the cohesive soundstage of the two older models. I suspect the earpads are to blame for most of this as they are virtually flat compared to the steep angle of the SR-Omega. As for the bass, it's either down to the diaphragm or there is a small port hiding somewhere in there. I suspect it is the latter as that "made in japan" piece is highly suspect. Ohh and this is a set that came from Price Japan and guess what, no channel imbalance....
  5. I will then modify it for Megatron duty...
  6. Sure, that would work too but I'd use 1W.
  7. 1W is plenty
  8. One label is incorrect but that's all. They are 2SA1486 in the - supply
  9. I needed a set to tune the new KGSSHV Carbon which will be designed specially for them. Also the price was too good to not get one.
  10. He ended up with my last KGST. Here I am listening to my brand new SR-009 which showed up today from Justin on my personal KGST after dropping Bob off at the hotel.
  11. Mine is still fubar so that won't be happening. Well we could do mono...
  12. If the CCS is toast then you couldn't adjust the offset and balance so it has to be working.
  13. There is very little drift in this design so the servo isn't as vital as with the KGSSHV but it helps as the tubes start to age.
  14. Try 1.37K or even 1.2K for the offset resistor. Running without tubes is a very good way to burn up the CCS...
  15. Yup, the gap factoring in the displacement and over all insulation properties of the air.

    The Bridge

    I like this show a lot, kinda liked the Tunnel too.
  17. Yup, built one in 2012 fully point to point. Sounds much better than the old version plus lower distortion.
  18. It isn't quite that linear and varies from driver design to the next.
  19. Given the issues we had with the resistor brand I'd guess so. Angle brackets are a good idea though. They support the boards and make testing far easier. Easy to drill by hand too.
  20. No schematic but it's just the one off Headwize with the phase splitter now a LTP setup.
  21. All the Stax electrets are pin compatible with the electrostatic models. Similar sensitivity too. Bias is a very relative thing and with transformer boxes you can have low bias but very high drive voltages. Not so much with amps.
  22. Something "new" for people to build. Fully balanced GES Mk2.
  23. The step up ratio of the Sony units was very high, at least 1:100 or even higher. Nothing Stax ever made will work with them. Electret films have a certain charge built in so you design the driver around that instead of the bias voltage. The bias voltage is the same principle, just different implementation. You can't recoat a electret diaphragm to use with an external bias supply.
  24. Gotta love the plate cap not connected to anything.
  25. Electrets cannot be be recharged as they won't ever loose the charge in the first place. Any imbalance has to have an external cause such as broken cable, parasitic charge on the film, damaged driver frame etc. The charge won't "wear out" in the foreseeable future. Never seen electret film for sale and I doubt you could buy just a small roll of it. It's interesting how it is made though, not something you can do at home.
