| noisy tube preamp after the unit has been on for several hours, like 24+ it will start to emit a high frequency pitch that also is only audible with no music playing but it is louder than the inherent noise floor of the pre.That is a form of something called 'mic... | |
| The ups and downs of tube vs. SS... Two audio shows really shaped my opinions on tube gear. One was a single ended symposium put on by Stereophile mag in the early-mid 90's in Philadelphia and it was the first time I heard SET gear. That day I heard 845 amps, 300b, 211, and 2A3... | |
| The ups and downs of tube vs. SS... I am a tube guy for quite while. I'm like to read articles concerning human hearing & perception of sound pressure levels and the effect of different levels of harmonic distortion on human hearing. Any suggestions?There is precious little a... | |
| KT120 back to 6550 If the driver tube goes weak or fails or is just way off from the tube you swapped out you lose bias and then it's all smoke and burned boards.@monoogan This statement is false. If the driver tube dies, the power tubes are held in cutoff and are ... | |
| Low-heat-output amp for Devore O/96 Thanks wlutke. Pass amps are high on my list, if I can find one that doesn't put out a lot of heat. Sounds like the XA25 might be the way to go.While being some of the best solid state amps made, it would be incorrect to say that Pass amps don't... | |
| Linestage types versus soundstage 1) What creates soundstage and is there something about tubes that gives them this ability?2) How is the signal leaving a powered linestage better than the incoming signal? I can answer that question for amps, phono stages and MC step-ups, but... | |
| The ups and downs of tube vs. SS... What are the ups and downs of both?In the end, its all about your investment. Tubes are hotter, and the power they make watt for watt is more expensive.If the closest you can get to real music is your goal, tubes are the way to go. If its anythin... | |
| Low level buzzing coming from tweeters. IMO, you are best served by complying with NEC and local codes. That usually requires stakes in the ground bonded to the ground in the service panel.@cleeds Actually I agree 100% with the code thing. Installing non-code grounds is asking for tro... | |
| Balanced cables They don't require shielding to achieve low noise.This is true- I've used balanced Kimber which has no shielding at all and over 30 feet, not hum/buzz whatsoever. | |
| TECHNICS 100th Anniversary 2018 Premium Turntables. Their best ever. I see the arm as a weak spot too. All my comments on the SL1200G are based on a Triplanar being installed, IOW they are about the platter and drive only. | |
| Balanced cables Warren Gehl to my knowledge does some very limited design work for ARC and is key in QC by reportedly listening to every piece of gear hooked up to his reference system of a Ref 6 and Ref 150se and some old, large Magnepans before the piece lea... | |
| Puzzling preamp problem Channel gain is not affected by break-in. It can be affected by being broken though :) | |
| Balanced cables but I’ve had the suspicion that instead of using differential stages they basically have a separate signal path through the amp (up to the output transformer primary) for each of the two signals in the balanced signal pair they receive for each... | |
| TECHNICS 100th Anniversary 2018 Premium Turntables. Their best ever. I have not tried the 1200G with a modern SME tonearm, so who knows what that could bring...I've set the 1200G up with a Triplanar, and the results were spectacular. | |
| Philips 212 Tone Arm issue Checking the arm wiring is a good suggestion. If its binding from the 'table being flipped over that could easily do it. |
