| Bias adjustment on solid state amplifiers If your amplifier is in for service, the bias is a thing that should be checked by the service technician (and its very likley that the technician will have to check it anyway if the service has anything to do with a damaged output section). Its n... | |
| AYRE VX-5 TWENTY- WHICH TUBE PREAMP MATCHS In order to really get all you can out of the amp you do need a balanced preamp as you've already surmised. But what most people don't realize is that there is a balanced standard; and that this standard is there to prevent ground loops and also p... | |
| Is there an affordable long run XLR preamp to amp cable out there? Atma-Sphere and BAT opinions are of little value unless you use their equipment.That is not entirely true. Some high end cable manufacturers obtain Mogami wire and re-brand it. The wire is oxygen free and the dielectrics are polyethylene; pretty n... | |
| Help me rebirth my old turntable i don’t understand why it doesn’t sound better unless it is not set up correctly or the needle is worn out. I probably will need someone with more expertise in turntable setup to take a look at this and give me an idea of what my next step sho... | |
| Cartridge Impedance The loading is strictly for the preamp’s benefit and does nothing for the cartridge.The reason it is there is because the inductance of the cartridge and the capacitance of the tone arm cable form a resonant circuit known as a tank circuit, which ... | |
| Help me rebirth my old turntable I should have googled it! Dual made some very interesting direct drive machines. Their motors were quite nice. | |
| Does anyone have experience with Bohlender Grabener RD 75 ribbon transducers? BG isn't in business anymore and the drivers have failure problems associated with tears in the diaphragm. If you have a set that works people are looking for them to replaced failed units. | |
| Zu Druid 6 As a Vietnam vet and infantryman the only thing M-60 means is the U.S . Army’s deadly machine-gun .If this was done for a laugh, it ain’t funny.The M-60 evolved out of the M-50 monoblock amplifier we introduced in 1991. We found that by installing... | |
| 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... |
