| Is there actually a difference? “Longtime readers of The Audio Critic know the drill that comes at this point: I repeat, for the nth time, that all amplifiers having high input impedance, low output impedance, flat frequency response, low distortion, and low noise floor sound e... | |
| Autoformer vs Speaker impedance Curve an Autoformer would work, because it’s one of the only speakers that presents a very benign 3-4 ohm impedance load.This statement ignores the fact that loop feedback compensates for this sort of thing.Atmasphere, regarding your link:1. In general ... | |
| Old Rek-O-Kut needs repairs but i cant find a proper manual any were. Yes the motor I have takes time to get up to speed. Could that be caused by the age of the capacitor thats in line with it?Could be. I had a Rek-O-Kut back in the 1970s and it had that problem then. Never sorted out the issue. The capacitor is a '... | |
| Atma Sphere deserves praise looks like the dealer link on the website is not working...FYI RalphThanks- got it sorted! | |
| Pre amps cost vs. value ... what I discovered last month. Wish I understood exactly how a pre-amp accomplishes this. Less phase shift and wider bandwidth. | |
| Old Rek-O-Kut needs repairs but i cant find a proper manual any were. You can get the idler rebuilt by Russell Industries on the east coast.I don't know why, but every one of these I've seen has had a motor that takes a while to warm up before getting up to speed- about 5 minutes or so. The motor and platter bearing... | |
| How do autotransformers affect sound? Okay. My understanding is that the output transformers in tube amps contributes to the difficulty they have driving speakers that have wild swings in impedance curves and phase (802D3). Power/voltage paradigm stuff. Even though we make OTLs, t... | |
| MAC Autoformers? But what about speakers with impedance swings all over the place, from 3 ohms to off the charts well at well over 20 ohms like 802D3s (nominally 8ohms). It’s swings like this that tax the best tube amps with their transformer outputs. How, exac... | |
| Autoformer vs Speaker impedance Curve What isn’t addressed is, what happens “electrically and sonically” with Autoformers when 8 ohm speakers, like 802D3s, dip down to 3 ohms or exceed 20 ohms??? With typical output transformers (common with tube amps) speakers with wild impedance swi... | |
| Class D is just Dandy! 1 - Direct Digital@erik_squires FWIW the phrase above is a marketing thing. It means that the amp has a DAC as its input, but the amp itself is actually analog, like all class D amps are. IMO/IME marketing terms like this tend to confuse the marke... | |
| Harman ST-5 Turntable RabcoTonearm and Cart I usually don't strip the wires used in an arm unless its Teflon and hardly anyone uses that! The heat of the iron is usually enough. I recommend SN63 as it will give you a better solderjoint than SN60! Tin the wires and connector first then tack ... | |
| Harman ST-5 Turntable RabcoTonearm and Cart As I recall that arm used a cartridge similar to a P-mount. The cartridge was probably sheared off in an accident and the 'table left for dead. Is the connector still intact? | |
| Soulution preamp DC-offset protection @katfnc I am now suspicious that this unit may be direct-coupled from input to output.If that is so, it could be that the source is the problem and not the preamp. Can you try a different source (cell phone for example) and see if it still misbeh... | |
| Electron Kinetics Eagle 2 Repair Help Years ago I fixed one of those that the owner managed to blow up. If its just filter caps and the like then its probably not that hard to sort out. Any independent shop (i.e. not Best Buy or the like) that can fix consumer electronics should be ab... | |
| Who makes the highest quality tube amps? Lets go with highest quality being equated to longevity.Any Dyna made in the old days will need refurbishment to sound right and be reliable; otherwise the power transformer is at risk. Dynaco went out of business in 1978; I bought one of their la... |
