Hi
I have a 40 year old Technics SU-VX500 that I've been using all that time, most recently as part of a home cinema setup.
We noticed a few days ago that there appeared to a problem with the sound output, so I did a little bit of investigation.
The problem appears to be concerned with the balance of the speakers. i.e there is no sound to the LHS speaker at all, even with the control turned all the way round.
Swapped the speakers and their cables over and the fault remains.
Somewhere along the line I changed changed tack slightly and discovered another vital piece of information.
If I use input via AUX (from my laptop) the LHS speaker does not function
If I use input from the Technics Tuner that I still have (tuner input on the amp) the RHS speaker does not function.
From the schematic I have the balance control is only a variable resistor affecting the sound signal.
I'm reluctant to bin the amp for such a simple (?) problem, so any help would be gratefully received.
Regards
Alex
