| LP: Left Channel Drops In and Out Could happen. The cutter is an analog lathe, so it’s definitely possible that the master for the LP was cut when one channel stopped working. These pressing masters need to be re-cut every so many LP's, so it's quite possible that in a large ru... | |
| SET 45 Amp Driving Dynamic Speakers If using a 45 amp to only reproduce 350 to 2000Hz on a 100 dB/W driver in a 25m2 room and if average listening level is 85-90 dB SPL, would a 45 suffice or be driven to the point where 5th order harmonics become an issue?Al did an excellent job... | |
| Output threshold using a Dynaco ST-70 amplifier with passive pre. Regarding Q1: the lack of dual rectifiers in this amp results in the rectifier tube being the number 1 failure mode in the amp as far as tubes go, if the amplifier is routinely driven hard.There are not any good solutions- if you go solid state, u... | |
| Joule Electra preamps and amps. What is your impression? It is Michael Green Audio Revolution 80i free resonance speakers. I've not been able to find any information on this speaker, but in general it appears that the speakers on Michael Green's site are pretty tube-friendly in terms of impedance and ph... | |
| Joule Electra preamps and amps. What is your impression? If you have a question about a speaker, just let me know what it is and I can let you know. The requirements for our amplifiers are similar to the Joules. | |
| Joule Electra preamps and amps. What is your impression? My older Sound Labs are very difficult to drive, but newer ones are easier, so I am not best to opine on that.Just a FWIW, sbank, there are some simple mods to the Sound Labs that make them a lot easier to drive and also better sounding regardless... | |
| Lyra Atlas experiences This delicate and extremely sensitive low output cartridge signal is degraded very easy and one form of that degradation ( exist several others. ) is the high noise in any all tube phono stage ( against any SS design. )If playing at a normal vo... | |
| KLH Model 11 Help ! The short spindle is either the wrong one or else it is jammed.Also, all of these machines I have ever seen suffer the same malfunction which has to do with skipping at the end of the record or the automatic cycle not working right. The fault is d... | |
| What's the benefit of balanced tonearm cables? I can clearly hear the differences in balanced cable....are you saying that balanced cables sound alike?They will if set up correctly. You might want to take a look at the Audio Engineering Society file 48 which defines the balanced line standard.... | |
| Joule Electra preamps and amps. What is your impression? Did I hear right that OTL amps require a very careful match with speakers ? In what sense? I read that some use them with big Sound Labs, Classic Audio's modern vintage speakers are apparently excellent match too. But that's big unusual speake... | |
| SET 45 Amp Driving Dynamic Speakers 2nd order can sound good to the ear. Enjoying our system choice is what its about not if its optimal or not, so if you like it dare I say its right.The concern of course is not the 2nd harmonic, but the presence of the 5th and above. 100 db peak... | |
| What's the benefit of balanced tonearm cables? The reason a balanced connection can have no cable artifact is the fact that the signal travels in a twisted pair within a shield (BTW this is how the signal travels in the tone arm- the arm itself being the shield). The shield is there for shield... | |
| Joule Electra preamps and amps. What is your impression? ^^Any amplifier using 6C33 power tubes will need the power tube sockets replaced on a regular basis. When the tube was used by the Soviet military, the recommended service life included replacement of the socket along with the tube. The socket was... | |
| SET 45 Amp Driving Dynamic Speakers When I checked my levels in the past, I didn't get much above 90 db on peaks. That was setting it as loud as I would ever want to listen. Most of the time, it was lower than that. 100 db peaks must be painful, not to mention the potential for h... | |
| What's the benefit of balanced tonearm cables? The reason you go with balanced line is to eliminate any cable artifact, and by that I mean that you may have noticed that some cables sound better than others. That goes away with a properly set up balanced line system.Balanced line and single-en... |
