Michell HR supply explained- "never connected "
"The Never-Connected approach takes advantage of the sometimes overlooked fact that the power supply actually takes up power from the mains over only a few degrees of the complete sinewave - the breif period in the cycle when the voltage on the secondary is higher than that on the supply rail, which is a necessary precondition for current to flow. NC's innovation is to isolate the equipment itself entirely from the wall during this part of the cycle by diverting the incoming current into a storage capacitor, then releasing it to the supply side once the AC current stops flowing."

An isolating power supply for electrical equipment comprises a transformer having an input for a mains alternating current (AC) power supply, a rectifier by which the output of the transformer can be rectified, and a primary energy storage device for electrically smoothing the output of the...

Never-Connected power supply

>the only excuse for not using batteries is the requirement for too high Voltages to run Valve Circuits< Another excuse could be the sound quality. I have a commercial, battery-powered IC-based phono amp which sounds rather good for what it is and what it costs. But when I compare it to an...

It was difficult to find the 3 pins connector mini DIN that Michell uses on its power supply. I found it!

It is made by Switchcraft. It is a Tini Q-G Connector, 3 pins, model TB3M, panel Mount.

Never Connected HR Supply circuit

Hi. I'm looking for the schematic or any technical information on the optionnal Michell HR supply for their DC motor turntable. it is supposed to be a great upgrade to the original small DC wall adapter. This HR supply is quite expensive. It contains what is called "Never-Connected" supply...

Regulated Supplies

Low power supplies, transient response

Simulert HR strømforsyning ,den reduserer ripple FØR spenningsregulator LM317med 2-3 ganger, men siden regulatoren i seg selv reduserer støy og ripple med 10 000 ganger , hvor mye betyr det om støyen på DC til motor reduseres med 10 000 eller 28 000 ganger? Hmm

R

0,01% wow tilsvarer ca 1/10 000 del av spenningen motoren krever... så DC spenningen bør være bedre enn 0.01% stabil...dvs 1/10 000 del. HR gjør i alafall noe, gir mer stabil DC til motor med mindre støy og er faktisk isolert fra nettet/trafoen.. peat to peak Ripple FØR LM317 regulatoren er 0.2% for standard supply og 0.07% for HR.
Men prisen er ganske ublu syns nå jeg 15 000 kr for en ringkjerne trafo og likeretting for ca 10 volt og 20mA er mye. Michell har et nytt bygg å nedbetale.. og kansje de har fått ekstern eiere/partnere som krever utbytte. Det er ikke mange år siden HR kostet 6000kr og Gyro SE kostet 18k. nå koster den 35k , dobling av prisen på får år..

litt om aniskateeffekt postet på ASR av meg

Some measurments of L and R distortion with 0 antiskate. 1.5 and 3 on my AT-OC9ML/II 1.5gram VTF on SME V on a Michell Gyro SE.
Clearaudio trackability test record 333 Hz lateral mono track
Seems like the SME setting at 1.5 is quite OK. The anti-skate function is still fine on this arm that is 30 years old.
With no anti-skating the cartridge jumps out of the groove at 90um

Prøver antiskate med blank plate. Trenger 30 % mer AS , det vil si 2.0 istedenfor 1,5 ved 1,5 g stift trykk.
Steve Hofman Naga Oka tråd


QUOTE="Balle Clorin, post: 36548397, member: 143049"]I got the blank disk method to work with this record Parks Audio demonstration here ATOC9MLii At 1.5 g I had to increase and this to AS setting to 2.o on my SME V to keep arm stationary, with less AS it skated inwards with more it skated outwards. My bad back does not allow me to look at the cantilever deflection just now.
Using the CBS record, ( STR-100 v3) I would get slightly too much AS 2.0 rather than 1.5 according to my arm and VTF 1.5g, ref post # 1144

See 17;:30 for blank method


@Ingenieur Is this OK for AS landing force. Looks evenly balanced at AS 1.5 and VTF 1.5g

husker ikke om jeg har lagt ut dette før..

Frekvensanalysen, ingen differanse på spillerne der- PU og arm e den samme, men armresonansen er ikke den samme på de to spillerne , it, men veldig lav resonans da , rett i det det stygge 4-6 området..her gjelder det å ha flate plater
