Default Yamaha Amp

Hello all,
I recently bought a Yamaha A-760 stereo amplifier in a second hand shop, it was cheap and thought I'd gine it a go to get it fully working.
After a bit of fiddling I got it working, all that's wrong now is that the panel lighis do not work.
Does anyone know fo a schematic for this amp or know anything about it.
Your help would be appreciated.

It's possible the lights are wired in series, so if one bulb has blown then none of them will light. Do a simple continuity check over each bulb.

That's very likely the case. My CA410 is wired in series.

Hi Dynsdale,
The lamps may be burned out - that's normal for this age. Did you check if there is voltage across them? Sometimes Yamaha will use the lamp to perform another function. Like the muting circuit in some of their receivers.
