Any Robertson Audio 4010 owners on Agon?

I Thank you both for your replies.
 
As I said in my post, the blue-lit on/off  switch is very hot, the top of the amp is not that bad. I am concern as to what is causing that switch to get so heated up?  
Secondly, how would you know it is time to change the caps, the amp sounds so good, you have to hear it for yourselves. None of the past amps sounded as good as this, that list includes, Adcom 555 II, McCormack DNA0.5, Levinson 431, Jeff Rowland 102.

 I am using an Advent 300 receiver as a preamp, and a pair of Gershman Acoustics X-1 speakers. 

rhljazz,

That is it, I am told by the original owner that amp has a bulb which generates lots of heat if left on for a long time.

Other then that, the amps sounds superb, super silent background,  smooth presentation, that perfect perfect detail, the tweeters "breath",  those bass notes that I thought never existed, that brilliant  control and timing of the musical notes, basically, all the musicians 'follow" the singer and play with him/her, my search for a power amp is over.

I would like to Thank once again to all of those who responded.

Cheers.
