This amplifier is almost 14 years old and is part of a set with equalizer, tuner, cassete player and a CD player with an optical connection. So, I am quite happy listening to it through my Bose acoustimass-5 speakers.
The only problem is that occassionally, the amplifier just stops and one can see a faint glow where the volume digits are normally visible. Over time, I have found that tapping it (quite hard with my palm) on the right side of the amplifier (while facing it), just little more than halfway towards the rear gets it going again. This has been going on for more than 6-8 years and I did not mind as it was my back-up system. Now, it has become my primary system again and I would like to listen to music uninterrupted.

Re: Suddenly dying Technics Amplifier SU-X520D
You will find that the output stages or power regulator stages have dry solder joints and may require some resoldering wherever you see them. study the whole board carefully, there may be more than one joint causing issues. If you are not well practised at soldering I strongly suggest that you get someone that can to do the soldering for you. Good Luck

For connecting these to your amplifier you need 4 Stereo RCA Cable.
1.Connection for cd: Take one of the RCA cable connect the one end (red/white) jack to the line out of your cd and connect the other end (red/white) to the CD input of Your amplifier.
2.Connecting the tunner:
Take one of the RCA cable and connect the one end (red/white) jack to the line output of you Tuner and connect the other end (red/white) to the TUNER input of your amplifier. 3. Connectiong the tape deck:
Now you have two RCA cable. Take one of the RCA cable and connect the one end (red/white) jacks to the PLAY out of the Tape deck and connect the other end (red/white) to the TAPE 1 play input of your amplifier.
Now connect the last RCA cable. Connect the one end (red/white) jack to the record input of the TAPE deck And connect the other end (red/white) to the TAPE 1 Record input of your amplifier.(this connection will help you to record to tape from cd or tuner. if you are not interested in recording then you can avoid this connection.)
Now you can select these three items from the frond plannel control switch of the amplifier.
Your amplifier is turned on and all the indicator lights work and you made it sure that all the cables, and cords are attached to where they are supposed to be connected and yet you don't get any sound coming out when you play a music. Amplifiers have selector knobs for you to set where your source is coming from. Selector knobs can be set to TUNER, DVD, CD, and AUX. The scenario might be like this: your source is coming from a movie being played on your DVD player connected to your amplifier but your knob selector is set to AUX. Try playing a music selection from your CD player attached to your amplifier and set the selector knob to CD. If still there is no sound coming out you need to have it checked by a qualified technician.
yes you can connect another cd player to the DAT input of your amp. input connections like DAT, TUNER, CD, AUX etc (except phono) is just to differentiate between what sources are connected, the amp cannot tell what source is connected and will output the sound no problem.
as for the remote operation, if the 2 technics cd players are switched on at the same time they're going to do what you command from the remote together but you'll obviously be listening to 1 at a time.
check volume balance between right and left-then change inter connection between sound source and amplifier with new cabel(i prefer gold plated type connectors)(see radio shack). after that if the problem excit your fault in output transistors or output stereo ic depend on circuit design.
its the ic that controls the + and - voltage and there are capacitors that have leaked all the caps on that board need changing could be expensive and time consuming but its the age of it . if i was going to do that job £200 plus\
