I have a deck technics RS-D5000 series which is powered from the amplifier. The amplifieir and the other associated equipments are lost yet i want to use this deck. kindly tell me which voltages are fed from the amplifier and whether AC or DC. IF YOU CAN GIVE THE ENTIRE CIRCUIT DIAGRAM I WILL APPRECIATE.

SOURCE: missing ac plug for receiver

If the AC plug is the standard "D" shape with the indents for polarization of the cord on both units, yes ou can.

The most common problem is a dirty record<>play switch inside the unit. Try this: Using a blank tape, press and release record/play buttons several times. This can clean the switch a bit. Then play a tape. If it fixes the problem, then you need to take the unit apart and use a plastic safe spray cleaner on the switch (Check at Radio Shack, their tuner cleaner Catalog #: 64-4315 will work fine). Spray it into the switch and then work the switch with the buttons several times.

Hope that helps...

SOURCE: power to technics rs-t24 dual deck

I own a RS-T24 as well and stumbled upon this thread while searching for this exact same solution. The RS-T24 generates no power on its own. It gets its power from, in my case, the SU-V75 amplifier. I still have a working SU-V75 and got the following readings out of the plug-in for the RS-T24 on the amp:

Left = pin 1 - (white wire)
Middle = pin 2
Right = pin 3

1-2 = 11.5 vac
1-3 = 23.0 vac
2-3 = 11.5 vac

SOURCE: How to increase (adjust) playback

The defect is in the Dolby circuits - the expander is badly adjusted. This is a well known problem for this model and the only way to fix that is to professionally realign it.you can't do that at home, only a very well equipped shop - with spectrum analysers - can do it.
