| McIntosh MT5 tonearm swap out? All tonearms can be wired for balanced operation if that’s your goal, including whatever comes with the MT5. | |
| TechDas Speed Issue You need your dealer or TechDas to get involved. There are no electronics geniuses here, much less even a run of the mill EE. I guess you should do the obvious checks, like is anything dragging on the platter? | |
| Phono preamp hum It's equally possible that by removing and replacing the tube, in your scenario, you improved contact at one or another tube pins, thereby curing hum that had nothing to do with the tube itself. | |
| Tonearm Mfg's mistake The Feickert protractor costs about $300 and will work for you for the rest of your overhung pivoted tonearm life, no matter what tonearm you may ever use. (And you can probably have one within a day or two from now, shipped within the US from any... | |
| Phono preamp hum I’m sure it’s an easy fix. But the fixer needs physical access to the unit. | |
| Phono preamp hum Your OP is dated 11/15, and on 11/16 you already have replaced the unit. Was this just a quiz? | |
| Tonearm Mfg's mistake Break down and buy the Feickert protractor, and you’ll never need another. It provides for all 9 and 12-inch tonearms. | |
| Phono preamp hum It could conceivably be a tube socket problem but unlikely to be the tube itself, although strange things do happen. I would try wiggling the tube gently in its socket or even just tapping it with the eraser end of a pencil to see if that changes ... | |
| Phono preamp hum It’s impossible to solve this sort of problem “long distance”, once you’ve eliminated the obvious. You did not answer the other obvious question; is your phono stage wall wart plugged into the same outlet as your linestage and amplifier? If not, t... | |
| Recommendations for MM Phono ~ Tube or Solid State Someday when you have a moment, read up on the trade-offs associated with using a transformer to increase signal voltage. In this thread alone, others have alluded to colorations related to the choice of wire used to wind the transformer, bandwidt... | |
| Phono preamp hum Have you checked the grounding? Make sure the ground wire is tightly secured. Then try removing the ground wire. Is your linestage plugged into the same outlet as the Bellari? If not, make it so. | |
| Phono preamp hum Does that unit have an AC filament supply? If so, I could imagine that there is a leak of AC into the signal that takes time to occur when you start from cold, because something needs to heat up before it leaks. It's important to know that this i... | |
| Is Rega the easiest turntable to set up.... Perhaps easiest to set up but also easiest to upset. (See what I did there?) Because of extremely low mass. | |
| Does Anyone Know the History of the Early Sota Turntables? Mulveling, Are you saying that your platter in effect bounces up and down on its magnetic suspension when sufficiently disturbed? So far as I know, the first fully maglev bearing is on the Verdier. SOTA have it now I think. My Kenwood LO7D platte... | |
| A Turntable History Question A very smart person I used to know hung his Advent speakers from his ceiling on springs. And yet, I would still claim he was very smart. Smart people sometimes do dumb things. |
