Olvasom itt a Technics lemezjátszók tápellátásával kapcsolatos okfejtéseket, és egy kérdés ötlött fel bennem.
Hogy is kellene elképzeni egy ilyen külső tápot? Egyáltalán gyárt valaki olyan tápegységet, ami Technics-hez készül?
Szerintem ilyenre nincs is szükség, mert hát bele van építve a lemezjátszóba. Ha viszont probléma van a fordulatszámmal, akkor azt orvosolni kell, és minden bizonnyal lehet is.
Pontosan.
Egyébként egy angol cég a Timestep reszel Technics külső tápot../meg sok egyéb baromságot/
De sztem leginkább azért mert előfordulhat,egy nagyon pici kimenő jelszintű MC hangszedővel,hogy a lemez vége felé közeledve,a tányér kb. közepén elhelyezkedő trafó "bezajosítja".
A Timestep ezen segít.
De pl. az én 0.3mV kimenőfeszültségű Dynavectoromat ez nem zavarja egyáltalán.
Ez jó! Egy quartz vezérelt motorelektronika elé bekötni mégegyet? Azt meg minek? Pénzkidobásnak biztosan jó. Biztos van rá valami szuper marketing szöveg.
Az ilyen trafó szórásra, gyógyír lehet egy tisztességes árnyékolás, márakinél ez jelentkezik.
KAB PS-1200GX
Complete Power Supply System
FOR TECHNICS SL1200 MK2-5& M5G
KAB began its relationship with the 1200 in1994 with our Broadcast Standard version which featured 78 rpm. We were thefirst to introduce the 1200 to audiophiles, when we added the TD-1200 tonearmfluid damping system in 2000. We introduced the very first outboard regulatedpower supply for the SL1200 in 2003. The PS-1200GX is our latest design toaddress the entire power system of the Technics SL-1200/1210 MK2-6 and M5Gseries turntables.
The PS-1200GX provides a very clean, quietDC voltage. It eliminates three sources of sonic contamination: Theelectromagnetic field and mechanical vibration of the internal transformer; andthe large peak-to-peak ripple voltage of the internal power supply. It is acomplete system consisting of an efficient power conditioner, updated internalregulator(DC-1200) and strobe lamp on-off switch(SX-1200). We never stop improving; The PS-1200GX is ourlatest solution to the entire power supply system and it sells for lessthan half the cost of old fashioned alternatives.
Since the PS-1200GX is external and no low frequencytransformers of any kind are used, all original sources of mechanical vibrationand low frequency EMF are eliminated. The 'table plays quieter. Sonically thisenhances low level resolution and intertransient silence. The PS1200GX can belocated close to the turntable without fear of hum fields radiating into thecartridge. This cannot be said for many of the overpriced old fashionedalternatives out there which house conventional unshielded low frequency powertransformers in non ferrous aluminum boxes. Pretty as they are, these designsactually radiate more low frequency EMF into your listening space than thestock original internal transformer! Over 10 years old, many of them, those oldfasioned designs are now, in our opinion simply overpriced, worrisome andtechnically out of date.
The KAB PS-1200GX meets the lateststandards regarding power supply efficiency. It is a green design that consumesless than 0.5 watt in standby mode. It works in any country, on all standardline voltages.
Forever improving your 1200, The place for state of theart performance and value will always

The 1200 original power supply has verylittle reservoir capacitance, 470 uF. The bulk of the supply filtering isperformed by the DC regulator, doubling as a capacitance multiplier. Thesecircuits are common, but they are not optimum. The PS1200GX system replaces theinternal regulator with our updated DC-1200
By incorporating a two stage choke filterand 4000uF capacitor, the DC leading into the 1200 is now a clean source ofpower. This lets the internal regulator do a better job of regulating the motorload.
Also, since the internal power transformer, isdeactivated, an additional source of EMI and mechanical vibration iseliminated. The turntable plays quieter.
The PS-1200GX uses no low frequencytransformers of any kind, eliminating all sources of low frequency EMF. Thekind that can cause audible hum.
Both DC-1200 and SX-1200 are included in our completepower supply system, the PS1200GX. As a complete system, the PS1200GXreigns a tight control over the power distribution within your 1200 assuringthe best possible performance.
