Question about Audio & Video Receivers
I have a technics RS-AZ7 Tape deck, the Left channel no longer plays? It is/was an expensive tape deck and I don't want to let it go.
Is it fixable?
The most common problem is a dirty record<>play switch inside the unit. Try this: Using a blank tape, press and release record/play buttons several times. This can clean the switch a bit. Then play a tape. If it fixes the problem, then you need to take the unit apart and use a plastic safe spray cleaner on the switch (Check at Radio Shack, their tuner cleaner Catalog #: 64-4315 will work fine). Spray it into the switch and then work the switch with the buttons several times.
Hope that helps...

Aiwa xx8100??? What are the missing letters? Maybe it's a source or preamp problem, eh?
I presume you have proven the channel is dead by trying multiple sources, swapping a different speaker onto it and that the balance control is NOT all the way to one side; headphones don't work either and we're down to proving it's dead before you take it in to a tech, right?
There is the slighest chance that a common control may have developed a high-resistance or 'dead' spot and is causing your symptom. Turn the POWER OFF and operate every control throughout its range a number of times, especially rarely-used ones like Tape Monitors and the Mute control.
If it still doesn't work you might want to prove if its a low-level signal loss or a high level amp failure. One way would be to run an RCA cable pair from the Tape Out to any other device (even a TV with speakers) you might have that accepts an audio input. If IT can't detect receive the DEAD Channel you
