| amp clipping earlier than usual? Ralph- yeah, more like 3db, noticeable. But if there's no distortion, and not a blown output(maybe yes?), what could cause that? My main concern is the transformer.The fact that the power transformer is running warmer is a bad sign and I agree w... | |
| Who makes this Pre-amp? Ralph, do you mean if it has tube regulated voltage, e.g., using OD3/VR150 type tubes, etc., or something else? How can one visually tell if a point to point wired preamp has regulated power supply? Thanks.Whether it is tube regulated or not sho... | |
| Amplifier current vrs watts; why is current more important? Unless you have a very benign flat impedance speaker (rare) that doesn't wander to much from being a flat impedance between 20hz to 20khz, only then is an amp with watts but little current OK.This statement is false.The impedance *curve* is not ... | |
| Supratek or Don Sachs - which way to go? 04-01-2019 11:22am:”I often recommend products that are not my own (as seen in this thread) [D. Sachs] and would be happy to recommend yours [Supratek’s] as well, provided I don’t have to worry about someone that took my recommendation getting mad... | |
| Who makes this Pre-amp? @cscrutinizerNot many tube preamps can drive headphones directly. Headphones typically have a 32 ohm impedance- that's a bit of a problem for tubes. Its a pretty short list as far as I know; our MP-1 preamp and the microzotl headphone amplifier ar... | |
| Supratek or Don Sachs - which way to go? @steakster It might help to know my perspective is also that of a service technician. I started working at the Allied Radio service department near my house the day after I graduated from high school. I continued to work in consumer repair while I... | |
| amp clipping earlier than usual? Hey Ralph. Actually, that amp seems to be down about 2db. I switched sides to check. I have several of these sets so I'm certain.You switched amps, so it follows the amps? (2dB isn't much but if you didn't use a sound pressure meter for that I be... | |
| Amplifier current vrs watts; why is current more important? I am not sure I understand your last statement. Are you saying that zero feedback amps can supply more current and would do better driving low impedance loudspeakers?No. I am saying that some loudspeakers (like Sound Labs) don't need a very low ... | |
| amp clipping earlier than usual? Does the system sound OK and the channel to channel balance is good?If so, it could be a problem with the indicator itself. | |
| Supratek or Don Sachs - which way to go? The internal photos comment, the advice to google the unit, that was low and uncalled for (in my humble view). So- a Google search on a thing is 'uncalled for'?? IMO that's a pretty low bar. As to the posting of the video on our home page that was... | |
| Supratek or Don Sachs - which way to go? Ralph, you might want to review all of your posts here besides the first one. I did. Are you reading more into my comments than is on the page? | |
| The Audio Gods are tough but fair-Have you had the "Curse of the 300B" ? The High End ndustry norm seems to be 85 to 88 db sensitivity and a 4 ohm nominal speaker impedance.Yeah- I don't get that. It doesn't matter what kind of amp you have, if you make it work hard its going to make more distortion, and with **any** a... | |
| Supratek or Don Sachs - which way to go? @atmasphere Having been a long time member of AudiogoN, I’ve always looked forward to reading your insightful posts. But, not the ones on this thread. Agree with @steakster have always admired Ralph with his very insightful posts but I think he ... | |

| Help me rebirth my old turntable I realize that trying to compare my analog equipment to my digital equipment is totally unfair. No- it isn’t. Typically LPs have more bandwidth than digital- going up to 35KHz is no problem for most cartridges and the LP mastering machines go up w... |
