OK...assuming that the thermal delay switch is non-operational...
So I removed the 47 ohm resistor, desoldered the wires attached to the tags that the resistor was attached to (presumably the switch part of the thermal delay) and joined these two wires together with a 2.5A connector block. Should I use larger?
Switched on and everything seemed to be OK but the volume seemed to be much louder than previously (as the current was now flowing directly rather than through the resistor??). Volume was so loud that I couldn't turn it all the way up to see if anything happened. the amp is connected to 8ohm mini-speakers which claim to be rated at 40 watts max power.
Have I committed any grave errors now? Should I go ahead and replace the diodes as suggested above?
