How much power in the JRDG#9? How much battery capacity? That'll give me some idea how long between charges.
I was just giving some 'considerations'. If you go with lead/acid or Nicad, you've got shipping weight to factor in, too. No Fair giving the UPS guy a hernia luggin 80lb of class 'a' chassis and another 200lb of batteries!
I work for International Rectifier, which has several class'd' entries, of which I own one. I am attracted to the battery PS simply because I don't have the skillset to design a good, clean PS, though I suspect I could build it if given a kit of parts..........
I can close to guarantee that the above amp had some problems. Perhaps battery storage with the fumes? That stuff is Really corrosive. I suspect that using some Optima sealed gel cells for automotive use may help. I further suspect the WAF is near zero. How you hide a dozen car batteries 'discreetly' is beyond me!
Thanks for the Info, which I'll look up. I have also seen, here on the 'gon, an amp called 'Emitter'.....something, which is a massive battery operated power amp. And, Massively Expensive, to boot. It is in the 25,000$ range, new.
My 'rule' is that there is NO bad topology of whatever ilk. Almost anything can be made, and made good / good sounding...some stuff just takes more development, parts count and is inherently more expensive. Arguing about what sounds better a SET or Triode or whatever tube philosophy is not the correct approach, IMO. How's it sound? Some arguements about this stuff is starting to sound religious.
