Deang Posted April 8, 2003 Share Posted April 8, 2003 ...is really cool. I had one of my amps out today taking a look underneath trying to figure out if there was anything in there that could be upgraded when I get some extra money. It didn't take long to figure out that the parts that are in there are really good. The only thing I could really think of was maybe uprading the rectifier with a HEXFRED. I decided to give him a call and I just asked him, "If YOU were going to do something to these amps to raise the bar a little, what would YOU do?" "Nothing", he says. "The parts are great, the transformers are great, it's clean -- I really can't think of anything I would want to do." After 20 minutes of chatting he loosened up a little and says, "Well, you know -- I did replace the one power supply cap, the one next to the choke -- with a 750 MFD, and it did tighten up the bass somewhat. What's in there now? A 300? Yeah, you could do that -- that would be good." He told me what I needed to do, and it looks like I'm going to have a really BIG ugly blue cap for each amp to go along with the smaller ugly blue caps. He didn't like the HEXFRED idea, saying he considered them unreliable over time. I also got a really good lesson on how a cathode auto-biasing circuit works -- for all the good it did -- as I only understood about 1/2 of what he said. A great guy who obviously knows his stuff and still loves doing it. Quote Link to comment Share on other sites More sharing options...
NOSValves Posted April 8, 2003 Share Posted April 8, 2003 Dean, You didn't write all this down or have the wife do the short hand deal shame on you. Stiffing up the PS filter caps is almost always a good thing ! Craig Quote Link to comment Share on other sites More sharing options...
artto Posted April 8, 2003 Share Posted April 8, 2003 Yeah, Mike Sanders is cool. He has worked with closely with Klipsch for many years. A Klipschorn owner himself of over 20 years. The quicksilver's are probably my first choice when & if I need to replace my Lux MB3045's. Mike told me he "always liked the sound of the MB3045".
