Technics SL-1210Mk2 Sound is very clear but low frequencies are very POOR.Other sources are checked i think the problem comes from the turntable. I replace my old phono pre amp with rolls VP29 and i check it with neumark cc-1 and shure m44-7 cartridges but problem is the same.Thanks!

It sounds like a bad connection to the cartridge, perhaps even the cartridge itself.

If the unspecified Sony has a "PHONO" input you should be good to go. What model?

"PHONO" is the only designated connection on an audio device that is literal and exclusive. Nothing but PHONO will work right on it and old-school turntables would require it to preamplify and frequency-correct the tiny current produced by a Phono cartridge. Look up RIAA equalization.

If your unit doesn't have a PHONO connection AND your TT doesn't have a self-contained preamp you will have to get a Phono Preamp to connect between the TT and any Line Level input, like Aux.

eBay always has some...

I'm havin the same problem,
did u manage to work out what the fix is?

Try fuse F1 / 250mA

this should help determine which one goes where but they may be the same , so it wouldn't matter if they have the same voltaage and amp. rating

Yes you can. You can purchase a TECHNICS DUST COVER here.

hi aris tomas...1st check the fuse inside the turntable..then if its ok go to the main board  ..check the zener diode (D3)  and the transistor Q3 and Q2...the fidbk me wat hapen , if possible if you can chance it replace it..u

Nope, the circuit boards have nothing to do with transmitting frequencies. There are only 4 items on the Technics 1200 that transmit frequencies...

1) Stylus/Needle
2) Cartridge
3) Tonearm
4) RCA Cables/Leads

If you've already replaced 3 and 4, the problem lies with either 1 or 2. Or the RCA cables you replaced were not done properly, or you used poor quality cables. Double check the work.
