Sony MHC-3500 problems
« on: June 03, 2021, 11:17:11 PM »
hi there -- I have an old Sony MHC-3500 mini hifi.
The cassette deck unit is long gone, as is the CD changer - they died a long time ago when the kids were little.

But now I have a pesky problem -- when I play audio through the Phono or Aux connections, I only get the right speaker. You'd think something is wrong with the speaker ---- but when I play radio through the Tuner, I get both right and left.

What can it be?

Thank you!

Hi asbefore...  My first thought would be the selector switch (phono/aux/tuner/etc.).  Try ?giggling? that switch or selecting various different functions ?quickly?.  Deoxit will probably help...

I suggest reversing the cables to see if the problem is your unit or the source component (or the cables)
Mac stuff, Sony HDR-F1HD AM/FM/HD tuner, Denon DRS 810 cassette, Denon CDR-W1500 CD recorder, Music Hall MMF-9 w/B&O MMC2, B & O 4002 w/B & O 20 CL, Revox A-77

And the balance control.   While you are in there, just Deoxit all of the switches and pots.

are you guys suggesting I open the unit up and Deoxit from the inside -- or just spray some deoxit on it from the outside without taking it apart?

the other weird thing is that this unit has a "surround" button on the amplifier, despite the fact that it only has connections for two speakers. I suppose it's "fake" surround -- but either way, when I press "Surround",  sound appears in the previously muted left speaker -- but it's not quite balanced.

thank you all!
