| 300b lovers The 300B ... all of them ... quite happily accept at least 20 volts of positive grid drive. This is not secondhand info gleaned off the Internet, I’ve seen it for myself on a Tektronix scope screen back in the Nineties. I was frankly surprised, b... | |
| Good Suggestions for Tube Amps under 6k In my experience, there is a spacious dimensionality in high-quality tube amps that I never quite hear in SS amps of the same caliber / price range. Texture and tone, particularly in acoustic and wood instruments. Also, the assured warmth withou... | |
| Don't sell your tube amps It seems as though I've heard this statement before.... 😉 Yes- I'm sure you have. I have too. What's been keeping tubes alive is how they make distortion. If you were to put the solid state amps on the bench that have been lauded for 'tubelike... | |
| 300b lovers @donsachs @lynn_olson @thom_at_galibier_design I confirmed a theory I had about OPTs over the weekend. You might give this one a try; its inexpensive. Replace the bolts that hold the OPT together. Typically these are made of steel and are insula... | |
| 300b lovers Conventional wisdom is that caps etc take a while to run in so do you have to run in the whole design for a a while to get the true sense of it and then tinker with the component parts thereafter.... and then wait for them to run in again before ... | |
| 45 Lovers - what are your favorite tubes? I use RCAs. There was a time when they were easy and cheap to find... | |
| Looking for high power warming sounding tube amps Whichever amp or amp class that the manufacturer or designer promotes at the time as the Holy Grail, will be the best sounding amp of all time. There is also the possibility that engineering was applied- the same sort of things that make airpla... | |
| Don't sell your tube amps Tube amplifier are on borrowed time due to a different threat. Its now possible to build solid state amps that are just as smooth in the mids and highs with no glare and the same sense of musical involvement. | |
| 300b lovers RM's minced no words in responding that 6SN7 tubes were a very poor choice of tubes -- "better employed in old TV's", because of their inherent high noise levels. @whitestix I encountered that with him as well- although by that time he was be... | |
| 300b lovers Ralph has written in the past that the 6SN7 is a sufficient driver tube “dependent “ on its implementation in a given circuit. I have been told that the 6EM7 provides much more current, power and drive capability compared with the 6SN7. I will s... | |
| Looking for high power warming sounding tube amps @smodtactical But what actual amp has those characteristics ? Our class D does. I think the AGD Audion does too. | |
| You've run some pretty fancy MC's, but the _______ MM cartridge really impressed me I was hoping there’d be some explanation of the preamplification being used, since ceramic cartridge output V is dependent upon stylus displacement not velocity. So ceramics don’t need RIAA filtering in the phono stage. @lewm If you look at t... | |
| Looking for high power warming sounding tube amps And, which amp would that be? An amplifier that has the same distortion profile as a tube amp of course. In case this is mysterious to anyone, the ’sonic signature’ of any amplifier is the distortion it makes. Tube amps sound the way they do ... | |
| Looking for high power warming sounding tube amps Id love something like that although im skeptical an SS amp can bring the tube magic the way real tubes can. I know of at least one such amp. | |
| Looking for high power warming sounding tube amps @smodtactical Does the amp have to be tubes if it has the same good character as a good tube amplifier? |
