| 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. | |
| A Turntable History Question And you could see actual rubber bands on full display? That sounds home-made to me. Such a suspension is like a spring suspension and needs to be damped in some way, else a disturbance would linger on. Then a second disturbance could lead to osci... | |
| A Turntable History Question Suspended from where? If you could see the rubber bands, I immediately had the image that it was on a shelf suspended from the ceiling by rubber bands. Because one cannot usually see the suspension of a suspended turntable out in the open. Eithe... | |
| Suggestions for phono preamp for LOMC's I always thought the definition (of RFI) depends upon the source, not the frequency of the spurious tone, but I will of course yield to your superior knowledge. Thanks. | |
| HumminGuru Orbit Vinyl Record Static Remover Nothing against the Humminguru, but the Zerostat should work too, if used properly. Trying to find the definition of "properly" on line can be problematic, I admit. | |
| Increasing a Low output MM I did not say that MI cartridges are universally unsuited to a SUT. True low output MI cartidges (let’s say <1.0mV) will still have about 100X more inductance than a LOMC of similar signal voltage output, but of course they can usually be mated... | |
| Increasing a Low output MM I guess if you could get someone to build you a SUT with a 1:2 or no more than 1:4 turns ratio, that might work. But I think it would be as costly as acquiring a different MM phono stage with more gain. | |
| Increasing a Low output MM Hello, doggy, but this is an MI with an output of 2.4mV. Which has commensurately higher induction than either of your cartridges are likely to have, since for an MI, votage output is proportional to inductive property, and again, the total gain ... | |
| Increasing a Low output MM Sorry. "Oberon", not "Overon". Like the character in Midsummer Night's Dream. There are several reasons why it would not be a good idea to introduce a SUT in the OP’s system. First, most commercial SUTs offer about a 10X voltage gain. If you incr... | |
| Increasing a Low output MM Overon. No. Don’t consider a SUT. |
