Amplifier repair/mod/upgrade in Orange County California?

So my beloved Accustic Arts Power 1 integrated amp is acting strangely.  Sometimes I do not get any sound from it at all.  The only solution which only works some of the time is to shut it off.  I am hoping it is a simple fix (op amp maybe?).  While I am it, I was thinking I could get the repair person to upgrade some of the components like electrical plug, fuse, etc.  

Any input would be greatly appreciated.
I could look at it for you if you brought it by but I live in Victorville CA 92392.
Thank you for the reply.  Victorville is a bit  far for me to drive, though if I do not have any other options I will keep this in mind.  Thank you again.

I could take a look at it for you, but may be as far away as Victorville for you.  El Cajon CA 92020

Good Listening


Thank you Peter.  Actually El Cajon is not too bad since I live in South Orange County.  Do you do modding as well???  I thought PBN Audio only made speakers???

Thank you Steakster.  I contacted Vintage Audio.  They are right up the highway from me so if he is the real deal it is the ideal solution.  Thank you again!
