Technics SC-CH550 stereo system - only the amp working

I have an old Technics SC-CH550 stereo system (separate units of CD, Tape, Graphic EQ and Amp but sold as one stacking unit) and when I connect it up and turn it on, only the amplifier unit comes on.

Could it be the flat connector lead (four heads on it in total) or something else?

I've tried connecting it up different ways around just to check I hadn't done it incorrectly

If it is the lead, does anyone know where I could find a replacement?

Thanks guys.

Hi

I belive that you have a lot of dust how is gatherd behind the system in the amplifier and it is preventing it to cool down you need to blow it clean and make sure that you keep the system gets cool air

if the temp in the amplifier gets to high it shut down the system instand of burning it very clever solution from the manufacturer

you have a very good system good luck

Technics SC-CA 1080 CD player jumps ,can I just buy any CD player separate and connect it to my technics? It's a separates 'style' system, not sure if its compatible with a different CD player


You have tried cleaning the lens? That might cure the jumps. Make certain your CD's are not scratched and clean too.

A separate CD player will work with your system, I think. It looks like the current CD player will connect via two phono plugs to the back of the system. Since the new CD player will have the same type, just remove the old connections and the power lead and plug the new CD player in the same phono sockets. As the new separate CD player will have it's own power supply it will not need the old one.
No further adjustments are needed. Any brand of CD player can be purchased.

Technics SA-DV290 Amp. Sound cuts out as volume is increased


hello it sound like the output ic may be in trouble you may have just dry joint on the ic which just resolder it . or there could be a capacitor leaking or they may have swelled up in which you will have to replace. it's best to do some visual checks first i'e look for any burnt parts any capacitor with bulging tops

It could be number of thing such as defective speaker, fan or fan control circuit, power amp fault etc. You can try to disconnect speakers one at a time and see if any of them causing a problem.

I don't now what settings to use on my technics stereo system it has 5.1 surround sound. My prob is I don't now what levals to set the speakers at for best results in the book it says I should hear bullets...


switch off pro logic/switch on supper suround/press button twice it will say MOVE:/
switch on Supper suround EQ then Vertual Rear suround then Multi Rear suround then Seat Position.they should be lit GREEN exsept Vertual Rear & center focus.
Seat Position should flash when it does move the curser in the middle of the jog dial.......... i.e UP:DOWN :LEFT :RIGHT .let go & it will set itself. then switch on the Supper s woofer on the amp to MID.

I THINK L.O.L

Adding equalizer to system


TIB's are notoriously rigid in their design. An EQ would go in between the source and the amplifer, typically in a Tape Monitor loop if a receiver is powering the speakers. This unit has nothing like that.

The manual implies you can record OUT to a tape deck and play it back (later) through the AUX but that does not mean you can send a signal out and get it back simultaneously as a real tape Monitor would do. Attached in the prescribed configuration, your EQ would be signal-starved as soon as you selected AUX. Dead silence would be the result.

Even if it was a true Monitor circuit, the change imparted would be to the entire program and anything down stream, including the subwoofer, would be affected.

A crossover could be used with a few high-end receivers or complete separate components and bi-amped speakers only.

Many people want to use an EQ with their modern multi-channel Digital Sound Processing gear but at best an analog 2-channel EQ (or any other processor) will only work with analog stereo sources. On most receivers, simply selecting the Tape Monitor disables all digital inputs. However, most DSP can still be employed with stereo source material and a 2-channel processor, with varying degrees of aesthetic pleasantness. Beauty is indeed in the ear of the beholder.
