| biasing for 4 ohm speakers The bias point on any tube is a DC value.The DC voltage drop across the output transformer is not going to change significantly even if the 4 ohm load is on the 8 ohm tap which it isn't in this case. The short answer:'No.' | |
| Zyx Universe. O.24 mv vs .48 mv with low eff spkrs My guess is that once you hear the Atma amps w a suitable speaker, your only argument will be w yourself, for not doing it sooner. IMO, the Salk speakers are beautiful, real craftmanship, but clearly designed for high power SS amps. A high(er)/fla... | |
| Zyx Universe. O.24 mv vs .48 mv with low eff spkrs Efficiency is pretty important if you want tube power, as tube amplifier power is more expensive. It also does not pay to work your amplifier hard regardless of the amplifier, not if you want to hear the best the amp has to offer.In my room with s... | |
| Speaker driver cone repair Midwest Speaker Repair, located in Roseville, Minnesota, has a lot of experience with this sort of thing. They have been in business over 50 years. http://www.midwestspeaker.com/ | |
| Amplifier is now off the Power Conditioner Most power conditioners made for high end audio do not work well with out power amps at all. In that regard you are better off plugging right into the wall. | |
| marantz 2225 stereo light If the stereo light is actually good, the most common problem is alignment. The tuning meter has a relationship to the ratio detector- if the ratio detector is out of alignment, the correct setting of the meter may not be at the peak. If the unit ... | |
| Are There Alternatives to the Marantz 10 B ? I've serviced all the tuners mentioned in this thread at one point or another. Even though these days my main business is building tube amps and preamps, I kept all my tuner troubleshooting gear from the old days.There are several points to keep i... | |
| Marantz 10b repair I always made up the opto couplers under the assumption I would never find the originals. Seems to me most of the time the neon bulb has failed and you can re-use the LDR. I wonder if that HiFiBruce ever got his sorted tuner out? Sounds like the d... | |
| Cracked glass/ Mcintosh Classic Audio Loudspeakers used to be called Classic Audio Reproductions, and did things like replacement glass for Macs. If its an older Mac you might check with him (John Wolff). | |
| 25 watts Class A or 70 watts Class A/B ? If you are open to tubes, our M-60 can drive that Tannoy with 60 watts... | |
| 25 watts Class A or 70 watts Class A/B ? Just a FWIW: 93 db is not considered high efficiency. It is a moderate efficiency. You are transitioning from moderate to high efficiency about 97 or 98 db.If the room is small enough or lively enough, I would go with the F5 in a heartbeat- it is ... | |
| Is it possible for a record to be too loud? Most preamps have a volume control at the input of the line section. This makes it impossible to overload the line section without also playing the system very very loud. So really if this is not a problem on all LPs, the possibilities are a probl... | |
| Cracked glass/ Mcintosh Right now fb has nothing to do with it. It is not your fault that he took so long to get back to you- not your fault if the amp sat damaged in a box until he got around to it or back in town or whatever. Its irrelevant.If the claim time has elapse... | |
| 25 watts Class A or 70 watts Class A/B ? If the speaker is only 93 db, a lot is going to depend on how lively your room is and your personal listening habits. My room is slightly larger but has some damping (carpets, LPs in shelves, couch and armchair) so 25 watts simply would not be eno... | |
| Capacitance settings on Manley phonostage With SUTs the traditional knowledge about loading does not apply.This is because the SUT has a turns ratio and must be loaded correctly to prevent ringing of the transformer. The correct load will vary depending on the impedance of the cartridge.H... |
