| Ordered a Willsenton R300 Oh I am sure people can upgrade them. Still, the poorly designed driver section is a limiting factor, even with better signal path parts. It could be improved by either CCS or choke loading of the driver, which would make it much better able to ... | |
| Ordered a Willsenton R300 will also depend on their output caps. The photo showed what look like your typical $5 Chinese MKP caps with their fancy labeling. Klipsch used caps that looked like that in the Cornwall IV crossover. Changing them to something like a vcap od... | |
| Ordered a Willsenton R300 Depends on how they are doing the DHT filaments. I use regulated DC and they may well have DC filaments? | |
| Ordered a Willsenton R300 Hi It is a push pull amp comprised of 4 individual SETs, 2 per channel. Class A, zero feedback of any sort. There are a couple of little tricks beside that, but that is the basic topology. The OPTs combine the two out of phase halves of each... | |
| Ordered a Willsenton R300 Hi, Don Sachs here. First, this is not an attempt at advertising in any way. The amp whitestix refers to is now in the second prototype and there is no commercial product. If you see a 300b that uses a 6SN7 to drive the 300b it will sound o... | |
| Primaluna? I paid the shipping, box was thrown around by shipper who seriously damaged it. I brought amp back here at my expense and repaired all damage. Then you didn't want it back so I completely refunded all of your money. Amp has been out in the worl... | |
| Primaluna? Look, I don't really care what amps people like or buy. I do care when people say things that are not based in fact though. I have no comment on the PL amp because I have not heard one. I can however, look at the photos of the inside and see w... | |
| Primaluna? Excuse me, but you did not have the Kootenay amp for any amount of time long enough for the caps to run in. So you never knew what it sounded like. Sorry, but comparisons with your PL amp are invalid. Don | |
| Line Stage Preamps that blew you away $2500 Edition Hi Don Sachs here. On the post above, the preamps will sound pretty good in 10-20 hours. I would say at about 50 hours, the tubes are run in and the preamp gives you most of the final sound. They really don't completely settle down for over 10... | |
| Best Way To Maximize Preamp Tube Life? Pulling tubes and running a circuit without all them in there is absolutely the WRONG thing to do unless you know exactly how the circuit is designed. You can destroy a filament supply (or a tube in it), or overwork a B+ (high voltage) supply if t... | |
| Best Way To Maximize Preamp Tube Life? Don Sachs here... turn them off if you are not going to listen in the next 30-60 minutes. Honestly, tubes last a LONG time in my gear. I run them conservatively. Now and then a tube dies early, but that would happen anyway, no matter what y... | |
| Klipsch Cornwall IV My thoughts exactly schw06. The speaker is an entirely different animal and I could never bear to hear the stock one again:) | |
| So where should the tubes be? My system is all tube. The Musical Paradise DAC has a chip of course, but the output goes directly to a tube output stage, then my preamp and my kt88 amp, both tube of course because that is what I build. I certainly have no desire to listen to an... | |
| Klipsch Cornwall IV or play most any Bill Evans live recording, or Oscar Peterson live, or .... well you get it..... Scale, power, and if you improve the crossover parts, the micro detail is amazing and no trace of brightnessThere are a lot of great speakers in the w... | |
| Klipsch Cornwall IV No, I am a tube amp, preamp, and phono builder, not a speaker guy. I have a pretty big list of things to build. I just do those other things for myself and really don't have the time for youtube or social media. I really wouldn't want to be res... |
