Intermittant speaker distortion on Technics SX PR602
I was struggling with the same problem with my friend piano. You need to replace check module which is plugged near power transistors. I found two bad transistors g109 and q119 (2SA1015). Changing those transistors and remaking soldering joints solved this problem.

used the same drive mechanism as your player. this turned out to be a
worn spindle motor and once replaced, all worked fine. you may well
have the same fault. hope this helps?

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
regards

You broke the ribbon connector that bounds your changer and tape deck to the sound processor (the black long ribbon that is permanently mounted to the tape deck) - the cheapest option is to get a new tape deck (around 20-£30 on ebay) or hount for replacement ribbon

DVD/Video CD/CD changer
The answer is simple if you want to listen to mp3 on your system and you purchased dv290 dvd changer you also need dv290 sound processor as they were coded - for example you have dv250 system with dv250 chager and sound processor you are only going to be able to see dvds and cds if you swap your changer to dv290 (plays mp3, audio ,wma and dvds) you also need to purchase dv290 sound processor as well - no need to change your amplifier or tape deck (the ribbon on the tape deck will be compatibile)
the lower end units were incompatibile with higher spec changers same when it comes to EH series if you have eh780 sound processor you are only going to be able to plug 780 changer or lower 760 770 etc... but 790 will not work with it unless you get 790 sound proc

Technics ribbon cable extension
You will never find those connectors, as they come with the ribbon cable, which is long discontinued. Rather than that approach, take the easy route. Just cut the ribbon in any place that you need the extension, add in your new ribbon cable, and heat shrink each and ever wire.

Hi,
please double check your wiring again as if you cross the polaritys (+ and -) you put the audio signal out of phase, thus casing cancellaion of things such as voices.

How do I attach and play a technics record deck to a technics DV250 amplifyer?
The problem you are facing is that the record player audio outputs has a left channel, a right channel and an earth or grounding cable. If this grounding cable isn't attached, you are likely to get a hum sound. I would suggest buying a record player RCA (Ground simulating) cable or you will have to buy an inexpensive mixer that supports record players through which you can channel this record player. Once you have all these, just follow the white and red color coding to attache the right channel to the right socket.
