Hi, I have as above an A_R 610, it has developed a problem where loss of sound/distortion appears on the right channel. pressing the speaker selector button in and out a few times temporarily (minutes to maybe hrs) sorts it. looking in the top all I can see is the bottom of a PCB to which I presume all the front panel controls are mounted. so unless a very simple job I can't repair it. Could spraying compressed air or contact cleaner in through the front sort it, or should I retire it?
Many thanks...
Many thanks...
There are many photos of the Teac A-R610, both external and internal, on this site: https://insidehifi.blogspot.com/2016/04/teac-r610.html
It is indeed a complicated beast internally!
I presume you are talking about the A/B speaker selector buttons underneath the input selector knob.
If you are considering squirting contact cleaner into those from the front I don't think it will solve your problem.
But if no other suggestions come up it sounds like you have nothing to lose by trying!

I see a myriad of little plug and socket connectors inside. Sometimes unplugging and replugging those can solve intermittent problems.
I missed your post. Have you tried my suggestion re the connectors?
You really need to get access to the switch mechanisms in order to clean them effectively.
Unfortunately that would require removing the front panel PCB which may not be a simple task.
However, you are only assuming the switches are the source of the problem - their operation might only be giving a jolt that temporarily rectifies a fault that lies elsewhere.
Such a shame, drewan, as it's such a nice amp.
