| Could someone with a Garrard 401 Measure for me... If you have a Garrard 401 why not do it yourself? | |
| Shelf life of EMT TSD 15 rubber suspension If the cartridge does not bottom out when set at the appropriate VTF the rubber damping is fine! | |
| What do the arrows mean on my cable? @esarhaddon : show me a physics textbook where wire directionality is mentioned and discussed. If such a property exists surely it would have been measured and quantified over the past two hundred years! | |
| SL-1200G Anyone Replace Arm and/or Power Supply? I am sure the Technics engineers have provided an excellent power supply. Why worry about it? | |
| Diffusion tweak The BBC LS3/5A used the KEF T27 dome tweeter which had a perforated hemispherical metal grill over the dome. | |
| NEED TO REPLACE OLD FAITHFUL- WHICH AMP. SHOUD I CHOOSE @spatialking +1! Power supply cap replacement is an easy repair. Why spend thousands on a new amp? | |
| Did you notice.... With streaming you are at the mercy of the services. They can use data compression to get their music streams to fit on the digital pipelines, particularly during periods of heavy usage. | |
| Need cable advice tome reduces mids Wire is not a tone control! | |
| Need cable advice tome reduces mids It’s the speakers that are at fault. Peak in the midrange. Use DSP to correct this. Don’t bother with an analog equalizer. These add phase distortion. | |
| Vinyl goes green! @pindac +1! I'm doing my part by keeping excellent old turntables safe from the landfill - including four Empires and two Duals! | |
| Opinions before purchasing @deadhead1000 +1! You get it! Adding subs to a room is not a panacea for bass! The results can be downright awful because of the excitation of room resonances, which no DSP can cure. | |
| Opinions before purchasing @mrskeptic : room size has everything to do with bass! As I explained above small rooms will not support bass below, say, 50hz. I used the reflected wave in my second example because it corresponds to real room conditions, assuming the back wall i... | |
| Tubes and GAIN on Cary Rom-808 I recall a good bias current for a 6L6GC is about 35 milliamps. This sets the amount of current (in watts) the plate/cathode can safely sustain. Excess current on the plates will cause "red plating" and will shorten tube life. | |
| Tubes and GAIN on Cary Rom-808 Bias refers to the operating current of the output stage of your tube amp. The driver tubes (12BZ7, 12AX7) use cathode resistors. This is called "cathode bias" and is not usually adjustable, so no need to worry about it. | |
| Tubes and GAIN on Cary Rom-808 The gain or amplifying power of a tube is called the "mu" factor. You can look this up in any tube manual. I don't have my GE tube manual at hand so I can't comment on the difference in mu of the 12BZ7 and 12AX7. I recall the 12AX7 is considered a... |
