A few minutes after I power on my amplifier it displays an F70 error message and asks me to turn off power. I power down and let it cool off. When I power up again I get the same error message a few minutes later.

I have a Technics SA-DX950, which has recently started displaying the F70 Switch Power Off message. At first it was after listening to some audio for a while and would reset when power cycled; now it's on power on, when either A or B speakers are selected (Speakers Off message when neither are selected). However, when you select DVD 6ch as suggested here, before the F70 message appears, the message does not appear and, indeed, you can play audio through the amp with the DVD 6ch Front RL channels. I would still like to fix the main problem with the amp, as I use the other input channels (e.g. phono).

I have a Technics SA - DX750 Amp Everytime I turn it on I get an error message F70 and then it requests that I turn the power off. This is all it does now, so sound. How do I solve this issue I have...

Hi!

The F70 error certainly indicates a blown fuse inside.
The real problem is why the fuse is blown: there are only two possible reasons
1. there is a short circuit on the output (lines or speakers)
2. you have a blown output transistor (and that means some work and skills to replace).

To be sure, please change the fuse with a same rated fuse (buy more than one because it can blow again). Disconnect the speakers and turn the amp on. If the fuse blows again, it is sure something wrong with the output transistors. If the fuse remains ok, then please check all the wiring to the speakers.

Hope it helped.

Regards,

Bogdan

Technics SA-DX950 intermitently sounds blown out

There are poor solder connections at the output amp pacs and the voltage regulators. Once these are resoldered the problem should go away. If you can solder, resolder any connections that appear grainy or have rings. If you can not, this should be effectively a labor only repair for any shop that works on audio gear.

Technics SA-DX950 has lost digital sound

This may sound like a silly check, but verify that the tape monitor switch is not engaged. What is the quality of the sound when turned up? Is the cound clear or raspy?

Technics SA-DX950

sounds like the speaker protection relay is operating probably from a dc condition appearing on power amplifiers outputs. probable cause is dry solder joints to the output stages. will need some reworking of the PA stage soldering to fix.
