| 300b lovers @alexberger Since an SET is a constant current load insofar as the power supply is concerned, it won't make much difference if you use tube or solid state rectification. But you might want to consider what happens when the AC line voltage changes.... | |
| 300b lovers I also bought 4 schottky diodes. What type of rectifier will sound better: a central tapped full wave rectifier or a bridge rectifier? @alexberger You might consider HEXFRED rectifiers. They are ultra fast, ultra soft recovery and so are less p... | |
| 300b lovers The tube Don, myself, and many other manufacturers would like to see go back in production would be a 45. @lynn_olson As best I can make out, Sophia and EML both make a type 45. | |
| What are the best GaN Amplifiers available today? Using Gallium Nitride FETs. Is this the same as GaN? @mjcmt Yes. | |
| Short? @mojo771 There is a bad capacitor in your air conditioning unit. It bypasses the power switch (in this case the thermostat). Because its failed, when the thermostat turns the AC on or off, a voltage spike that is supposed to be snubbed by that cap... | |
| Current production 45-type tubes @lewinskih01 There is a TJFullmusic 45 that is worth checking out. https://diyhifisupply.com/product/tj-full-music-45-n-mesh-plate-domematched-pair/ | |
| What are the best GaN Amplifiers available today? How do these various GaN amplifiers perform at low volume (ideally, when paired with speakers known for low volume performance, e.g. horns, BBC monitors, etc). I can't think of a reason why they wouldn't work just fine. For starters class D amp... | |
| Tube arch So actually what u are saying is that when a tube goes bad it will always ARC ? And will take out a resistor along with it ? Is this on all tube amps ? Or Audio research? @tattooedtrackman Arcing is the primary failure mode of modern power tube... | |
| What are the best GaN Amplifiers available today? I found out later that Class D amps and linear power supplies don’t really go hand in hand, for reasons I forget why. @blisshifi There isn't a reason. The kind of power supply makes no difference if its properly designed. We use a linear supp... | |
| 300b lovers Why is so much harder to drive 300B? @alexberger Mostly because of the voltage swing. RC coupled circuits are a bit inefficient if you also want current to deal with that input capacitance (which admittedly isn't all that much). That is why tr... | |
| Tube arch I’ll keep this short. So my last post was about a tube arc. Took out a resistor on one of my Audio Research Ref 750s. I replaced the resistor and put in a matching KT150. My question is how can I avoid this from happening again. @tattooedtrackm... | |
| Balanced/Differential tube preamplifier recommendation? @thought9 I get it- back in the 90s we studied the remote issue for years; nothing was out there are the time that was at the level of our master control in the MP-1. So that remote didn't show up until the early 2000s. The MP-3 was harder due to ... | |
| Balanced/Differential tube preamplifier recommendation? @thought9 Yes, if a 4-dech control can be considered 'regular'. Turns out that due to a change we made in the volume taper about 8 years ago that the difference between the stepped control and the pot was mostly eliminated. | |
| Balanced/Differential tube preamplifier recommendation? Why can't the existing attenuator be motorized? @thought9 The control has to have 4 decks because its controlling both the inverted and non-inverted phases of the signal. The stepped control has to not exceed a certain size. The switch we use c... | |
