Broken input socket but I noticed a burnt 2W resistor.
Uses 100W TDA7293 , no mention on ST PDF manual of this R-C snubber?
between speaker output and ground. 100V,1uF cap in series with 2W
resistor,
measuring existing sections maybe was 3.9 ohm , anyone happen to know
correct value .? Or hazard a suggestion , obviously not too critical as
probabably months of use with it being at near infinite resistance, metal
oxide , does it increase or decrease in value on excessive heating ?

Replaced with 8.2 ohm, 2.5W vitreous with extended down the traces soldering
in the end, as ST don't seem to think its necessary for a mains bourne surge
dv/dt snubber ,or whatever its function
