| Why are there no high end cheater plugs? I can't imagine lifting the ground on my tube amps, which use a 2500V power transformer and run at 2300V plate voltage...instant death from a ground fault. Instead, I made a parallel earthing conductor (PEC) from 9 gauge Cardas copper litz wire, w... | |
| Can headphones ever be as good as high end stereo? My solution to the wife volume problem was to buy a ranch-style house. She goes to the bedroom at one end of the house, my listening room is all the way at the other end.Sometimes the best way to keep it together is to keep yourselves apart! | |
| Suggestions? Tubed linestage pre-amp?? My vote...build your own. You can build a preamp that is as good as or better than anything commercially available, because you can build it exactly how you want it to be, using top-notch components, and you don't have to worry about the commercia... | |
| What's the greatest bargain in SET these days? Depends on the SET what you can drive. I have no problem driving 85dB (if that efficient) Infinity RSIIb speakers with an SET, to louder than I'd ever need. Just need lots of power supply storage (400+joules), 2500volts B+ and 62lb output transfor... | |
| PS Audio Power Plant P10 question I run two P5s which gives me more capacity than one P10. I use one per channel of my amps (homebrew 200wpc SET amps) and divide the other stuff up as evenly as possible between the two units. They each run at 82-83% of capacity and all seems well ... | |
| Speaker grills Off when playing. On otherwise to help prevent yellowing of the PP woofer cones from sunlight.Makes an audible difference to me in the treble. Infinity RSIIb. | |
| Capacitor log Mundorf Silver in Oil Those Solen caps also measure very well on my LCR meter, with a dissipation factor that's borderline unmeasureable. Actually quite a bit lower than the Duelund CAST I've measured. Of course that's not the only important factor for a cap but it is ... | |
| Capacitor log Mundorf Silver in Oil Here's a bit of heresy. I actually think Solens sound very good in the lower frequency ranges. I have them in the woofer (<150Hz, 200uF) and low midrange (150-800Hz, 70uF) circuits in my RSIIb speakers, and the sound is excellent. Far, far bett... | |
| 300B PSET Agreed that power supply is critical, after all the power supply is what you are listening to, the rest of the amp is just there to modulate the power supply to make a higher-power version of the input signal.For example, my 833C SET amps have 400... | |
| Which high power SET By the way, the actual schematic of the build differs slightly from the one in the first post of that thread (evolution!). The actual amp uses the AOT2N60 instead of the original AOT1N60 for better power dissipation, there are gate to source prote... | |
| Which high power SET 06-30-14: AtmasphereThat is quite impressive to get that sort of bandwidth out of an SET of that sort of power! Do you know the configuration- by any chance is it a parafeed circuit?---------------------------------------------------------I design... | |
| Which high power SET Atmasphere,Small signal bandwidth is 7Hz - 66kHz, -3dB; the OPT is of course the limiting factor and those are the actual test results provided by Monolith Magnetics. When I checked the amp with a .05V signal using TrueRTA on my laptop, which only... | |
| Which high power SET Al, they have an output impedance of about 1.2R, which is in large part due to their 13K : 4 output transformers (Monolith Magnetics S-833); they spec them at 12k:4 but my measurements say 13k. The OPTs weigh 62lbs each and have an amorphous doubl... | |
| Which high power SET I guess Atma's point also has relevance to my situation, as 20% of 200W is still 40W, which should be able to push my speakers to a little more than 100dB, which is pretty loud.The bonus is that at 40W, the amps are still in Class A1. Above that t... | |
| Which high power SET I run 85dB (if that!) Infinity RSIIb speakers with a homebrew 200WPC, zero NFB, SET amp and it's the best sound I've ever heard. Crystal clear highs, full lush mids, rock solid thunderous bass. Sounds like a fleawatt SET, with twin superchargers!U... |
