So i have a Technics SA-DA10, which was working fine, until one day the unit suddenly decided to distort my CD analog input. It's not a Marshall, but it distorts, especially in the low end, and it sucks... Weird thing is, the digital inputs still work like a charm, be it from CD, or surround DVD or whatever else. Only the analog ins have this problem. Anybody has an idea what could probably cause this? All suggestions welcome! Thanks in advance...
Re: Distortion on analog input of Technics SA-DA10.
Solved it... Turns out it was the connection between my "Tape Out" on my DA10, and "In" on my (Philips) DCC deck that caused some sort of (ground?)loop. Removing this connection solved my problem. Can't believe it took me so long to figure this out! Anyway, i'm very happy with this, since i really love this amp, and i felt really bad about this sudden weird distortion thing. My faith in the Technics brand has been restored, as has my appreciation for this lovely piece of gear :)
I had the exact same thing with my Technics SU-A808 stereo amp, btw.

what connections do you use for the device you are listening to, and what device are you listening to when this happens. you should use either an analog, or a digital connection to a device, but not both
Ahh technics. Technics always had overheating problems, trust me. Every since they started, their amps would get so hot they would hurt to touch. The reason the fan is not coming on seams to be something inside the circuit board. I'm sure that technics could fix this. If the fan works out of the receiver, then it must not be the fan. ;P
I would maybe get a computer fan, and just put it on top of the receiver and turn it on, or send it in for fixing. Also, do you have to crank the volume to get the speakers to play at your volume, and does the impeadence match the receiver. Because you may be pushing the receiver too hard.
I have a Technics SA DA20 control receiver. I was given it by an electronics workshop and it has this same error of OVERLOAD coming into the display when switched on. I removed the plates from underneath and re-soldered as far as I could all the points along the stereo amplifier ICs and as far as access would allow. The unit then worked normally for several hours. I was very pleased, and went out shopping!. But on my return after it had been off for about an hour, the same problem has come back. But my boss at the electornics workshop thinks it it just a dry joint, or series of dry joints. The unit is complex to dismantle, so patience and care is required in taking it apart and making a note or diagram of how it comes to pieces and how to re-assemble it after the board has been re-soldered. It does not appear to be a component problem or fault with the SVI power amplifier ICs. firstname.lastname@example.org
Cracked solder joints due to excessive heat cycling. Do not place in a shelf system. Top MUST be open for 1 ft. or better for proper convective cooling effect. Mine suffered same fate but repaired locally.
