Replacement for loricraft power supply

Actually, there are no variations on the Lenco L75 motor that I know about, but I could be wrong. Perhaps other Lenco tt's (other than the L75) would use different motors as a matter of course. I look forward to receiving my Kelly controller in the near future, with some excitement and interest. Of course, as I told Mark, I think of his product as a Lenco Motor Controller.

First of all, the turntable will "work" without any antecedent power regenerator. So why not enjoy your Garrard while you continue your search for one? Second, I have a hunch you are one of those who were waiting for a Mark Kelly supply, like me. I have been using a Walker Audio Motor Controller, first on my Nottingham tt and lately on my Lenco, with no problems. (I had intended to use Mark's controller on the Lenco, in the belief it would better the Walker, but that idea is out the window.) You could opt for a Walker controller or a VPI SDS. Like Mark's controller, the Walker is single-phase. Too bad about the IC in Mark's build.

Those two will work with any single phase motor. They will "work" with other AC motors, also, but not as well as a dedicated 2- or 3-phase controller.

I am trying to get a response from Mark on the KT88 based controller, price and ETA. Do you know anything?

Dear Steve (Vetterone) thanks for the enlightenment. As a Lenco owner and user, I had heard the scuttlebutt around 50Hz for the Garrard, but never from an authoritative source such as yourself. The Lenco motor has no such idiosyncracy, to my knowledge and based on my experience. I guess/assume Mark's stillborn solid-state controller was going to allow for frequency adjustment, as well as voltage. Obviously, the Walker and the SDS do not allow that. Sorry if I misled anyone.

Andarilu, I kind of agree with you; using the Walker on my Lenco, the main benefit is an observable improvement in speed stability (using the Sutherland Timeline and the KAB strobe as measuring tools). However, I do not hear as much of an improvement in sonics with the Lenco as I did with the Nottingham Hyperspace. I could not believe my ears the first time I hooked up the Walker with the Notts; it was akin to a major turntable upgrade. Not so much with the Lenco, but the speed IS observably more stable, and as you say, switching to 45 is no problemo.

P300s and later versions are still readily available. I've never played with one, but I think someone told me that the frequency adjustment is only a few Hz up and down from a center frequency of 60Hz, so it may not get down to 50Hz. But this is hearsay.

Steve, The solid-state Garrard/Lenco PS that Audioblazer and I had on order from Mark Kelly was to be a completely finished product, as received by the end user. In fact, he built them and recently sent me a photo of a completed unit. But at the last minute, literally, he found that the key IC in his prototype unit failed prematurely, and he is now unwilling to go forward with the product at all. Those of us who had one on order have been offered the option of a tube version, using KT88 output tubes. The latter is also far along in development and build, according to Mark.

Mark, Sorry to have let the cat out of the bag, as it were. There was no intent on my part to embarrass you in any way. In fact, I admire you for not going ahead with the SS controller, if you had doubts about its long term reliability.

Chris, Is there such a thing as a discrete "60 Hz" winding on the Garrard 301 motor? Did not know that.

Farancon, What is your definition of a "power stabilizer"? Are you talking about an AC line filter, or an AC regenerator, or what? Thanks. There really is a consensus of informed opinion that suggests there is something to be gained by being able to control line frequency and voltage, so as to get the G301 motor to operate with minimal vibration while preserving max torque and speed stability. I do not own a 301, but the argument has a parallel with respect to my Lenco idler as well. To be sure, you are quite correct in saying that such a device is not at all necessary to use a 301 (or a Lenco). It's just frosting on the cake but very tasty frosting for sure.

Chris, I would not have counted the capacity to take different input AC voltages and frequencies as a difference in the motor per se. But I surely agree that those variations are said to exist.
