| Grounding Question @chayro Lifting the AC ground is a thing that people do to eliminate ground loop buzz. Its an indication that the grounding scheme of one or more components in the system isn't well thought out. You can test for this sort of thing using a Digital... | |
| Bedini Amp repair Any shop with a technician competent with 1970s-1980s solid state should be able to service this amplifier. If probably does need new filter caps but I doubt that is why one channel 'went fuzzy'. The biggest issue working on these IME is getting ... | |
| Replacement for Carver Crimson 275 to drive Maggi .7’s are you implying that the Carver Crimson 275 only puts out 15 watts in real applications? If so please explain. The amp weighs 19 pounds. It would be something of an output transformer miracle if the amp were to actually make the power claimed ... | |
| When someone tells you it's a $40,000 amp, does it sound better? On the other hand, with an easier speaker load sans passive cross-overs, not least with speakers more efficient, you have a much better outset with less power needed to accommodate topologically more simple and cheaper amps, while maintaining the... | |
| Tube preamp options I am not sure that is 100% a certainly… The cartridge can feed out as balanced or wired to be single ended. I am pretty sure that it is possible to bring in the RCA into a balanced preamp with a custom made cable. (I have done it.) Sonically it ... | |
| Tube Amp for Devore O/96 I have some research to do I suppose as I don’t know Class A from Class AB or what a pentode is. Triodes get their name from having three elements- cathode, grid and plate. Pentodes have two more grids as a method of increasing efficiency, but ... | |
| Atma-Sphere Class D… Amazing I see Bob hasn’t responded. Do you have a couple photos of your class d amp with the black faceplate that you can post…or link to? No- there's not that many built with black so far and none in house. It didn't occur to get some shots of the bla... | |
| Tube Amp for Devore O/96 Ralph I’m surprised you didn’t explicitly support my mention of your S-30. I know the 0/96 may dip slightly below 8ohms in a few frequencies, but might you have any opinion on how the S-30 might perform with the O/96? @blisshifi I appreciate th... | |
| Grounding questions Aging a ground to that was not part of the contract. That is why I am now considering having a ground added. @mschott FWIW dept.: in order to add a circuit of any kind, whatever it is connected to has to be up to code. So either the electrician... | |
| Harmonic distortion inquiry Does the THD of each individual component accumulate, or is the effect limited to the highest (noisiest) one component? Simple example question; if each device has .03% of THD for a phone pre-amp, pre-amp, and power amp, is the system distortion ... | |
| Atma-Sphere Class D… Amazing Will the Atmas Class D be playing at Capital Audiofest? Hoping so. @mapman We're hoping to have it there in the Classic Audio Loudspeakers room. I won't be there. | |
| First Watt SIT3 vs Dynakit ST35 I've always had a soft spot for the ST35. I seriously considered finding one or building one up from scratch when I was looking into an amplifier for my bedroom system. But I realized it would be too large both power and size-wise so I built a sm... | |
| Microphonic from Vacuum Tubes? So far I've only experienced this issue while streaming from Tidal or my own MinimServer running on my NAS. @xcool Really! That is telling you something. In that case play the LPs only for a week. If you don't hear any pops, I'd look into is... | |
| Tube Amp for Devore O/96 @flipturn That speaker is easy to drive so you have a wide range of amps to choose from. Its not efficient enough (unless you have a small room) for SETs (which should not be run past about 20% of full power in order to avoid excess distortion) un... | |
| Microphonic from Vacuum Tubes? I'm inclined to think that the culprit could be something with the preamp or the new tubes. @xcool When you make a change and things go south its a good bet that the problem is associated with something you did. However, that bet can also bl... |
