kevin gilmore Posted July 26, 2009 Report Share Posted July 26, 2009 latest singlepower clusterfuck here Supra Schematic? - Head-Fi: Covering Headphones, Earphones and Portable Audio and a smoked singlepower supra extreme slam se with pictures soon. If the person that is going to fix this is as good as i hope they will be, then maybe we can find a way to get him to drive over to mikhail's with a truck and pick up all the dead stuff and then charge people to fix it. He is only 75 miles away or so... Quote Link to comment Share on other sites More sharing options...
Voltron Posted July 26, 2009 Author Report Share Posted July 26, 2009 Ironbut really did it! I finally have proper tubes in all locations and he really fixed the damn thing! I tried with some crap tubes because that was all I had in SF and they sucked and there were problems with the sound and drop outs etc. as I mentioned above. I then borrowed a couple mismatched 6sn7s from blessingx and it was better but Ric said one was suspect and he was right. Today I went to Mayberry to get my tubes and I put in all good tubes and the beast is back! It sounds great without any problems, distortion or anything else to get in the way of the sound. I am so relieved and psyched to have this resolved. No more meets for this frail flower and if anything further goes wrong then the KG design is going into play. Thanks again to all who helped but special props go out to the miracle worker in iron. Quote Link to comment Share on other sites More sharing options...
luvdunhill Posted July 26, 2009 Report Share Posted July 26, 2009 Cool! If you're looking down the road to just try the KG supply for the heck of it, I'd love to have a go at it for you. I have a few ideas of my own but they are in early gestation stages... and involves, among other tubes, a 12AX7 in the PSU for an error amplifier, which could be sorta weird for people... but, maybe I could just barely gain the KG seal of approval Just for the heck of it, I'd like to know the output voltages and currents though, if anyone happens to have a rough idea.

Voltron Posted July 26, 2009 Author Report Share Posted July 26, 2009 I don't have a clue what you are talking about but that would be fun! We should talk when you are not traveling and maybe you could have it as a back-burner project I would fund. You get to experiment and I get to have an alternative flavor of amp and a backup. Win. Win. Hope you are enjoying the road trip. Quote Link to comment Share on other sites More sharing options...

kevin gilmore Posted July 26, 2009 Report Share Posted July 26, 2009 My personal amp is a ppx3 extreme. Back then mikhail built about 50 mpx3's and ppx3's and was unable to sell them. So he tore them apart and rebuilt them as extremes. Including the completely underpowered transformer. There are only 3 different chassis sizes, and 2 different circuits total. Plus all the custom stupidity. (dynamic amps only) My tube power supply design was such that it used existing tube socket holes, and did not require any chassis work. I can certainly build all tube power supplies that regulate to a fraction of a volt. Basically copies of the old tektronix stuff. Requires very custom transformers with lots of isolated taps. Would not fit in that box. Quote Link to comment Share on other sites More sharing options...

So he tore them apart and rebuilt them as extremes. Including the completely underpowered transformer. I had him rebuild my ppx3 into an extreme. Mine is the platinum version with the plitron transformer. Do you have any idea of what plitron Mikhail used and whether it is underpowered too?

kevin gilmore Posted July 26, 2009 Report Share Posted July 26, 2009 You just think that it is a plitron transformer because you have been told it is. Given the events of the recent couple of months, how do you really know unless you pop the cover and look. plitron transformers, every one i have ever seen going way back are all toroids and won't fit into the square box. So if you still have the 4 inch x 4 inch square box there is no way a plitron toroid is going to fit in there. If you have the round cover then there is a good chance you really have the right transformer. Then there is the issue of what particular model number it is. Here is a big hint. Nothing mikhail has ever done that i have seen so far has custom transformers, everything is a stock model. His line that he had the transformers custom made is pure bullshit. If the transformer runs so hot that you can't touch it after it has been on for an hour, it is likely that sooner or later the transformer will let go. When that happens a custom transformer is about $107. But then it ends up looking like mine does now instead of what it used to look like.

kevin gilmore Posted July 26, 2009 Report Share Posted July 26, 2009 I've just looked thru all the plitron standard product and there is no standard part that comes even close to the required power and voltage requirements. So if it really is a plitron, it would have to be a custom thing. Something like 120vac output at .5 amp, and 6.3vac at 10 amps. Quote Link to comment Share on other sites More sharing options...
n_maher Posted July 27, 2009 Report Share Posted July 27, 2009 Kevin, Even the plitron model Extreme's still wouldn't support the big output tubes and required an external power supply for the 10A filament tubes. So I'd expect the Plitron to carry 120V/.5A and maybe a 6A filament winding. I still don't see anything that looks right in the Plitron listings...

Voltron Posted July 27, 2009 Author Report Share Posted July 27, 2009 After sweating out some odd distortion/static since late last night, I finally realized that an update to the Amarra software had somehow pegged the main output in the red. I thought I was going nuts, especially since mostly low-rez files showed the static and the Luxman made it much less noticeable or not noticeable on some tracks. Oddly enough, it just goes to show how resolving the SDS-XLR really is. Quote Link to comment Share on other sites More sharing options...
tkam Posted July 27, 2009 Report Share Posted July 27, 2009 Or the Luxman just isn't resolving at all Quote Link to comment Share on other sites More sharing options...
Augsburger Posted July 27, 2009 Report Share Posted July 27, 2009 I doubt that. The short time I had it hooked up to my Audio Aero, it seemed very resolving. Quote Link to comment Share on other sites More sharing options...
