Any Robertson Audio 4010 owners on Agon?


Hi, 

I was wondering if I can get some help. I recently purchased this classic Robertson 4010, which works great. 
However, I have noticed that it gets really hot after two hours , even when it is on only and you are not sending any signal thru it, the blue power on/off switch gets really hot to touch, is that normal, or shall I take it to have it properly checked out by a certified tech?
I am hoping someone here would throw some light on this. 

Many Thanks

Cheers

No experience with your amp, but on a product that old, it likely has a bulb in the switch instead of an LED.  The bulb will generate heat.  Another possible factor is the switch circuit.  The switch might be wired to full current rather than a relay circuit.  That will also make the switch warm.
