    @kabot_avez,

    I don't know of any vintage amp technicians in or near Tulsa, but I can recommend that you contact:

    Jeffrey Jackson

    He does excellent work at a reasonable price and is a pleasure to work with. He is an expert. He is completely reliable. He has completely rebuilt amy Perreaux SA33 preamp (~1989) and Perreaux PMF3150 amp (~1989). The preamp and amp both perform flawlessly. The shipping both ways from New Hampshire to Missouri was easy.

    Other than the fact that Jeffrey has performed this work on my equipment, I have no affiliation with Precision Audio Labs.

    That's great to hear that he did quality work Moose. Looks like Jeff's business is no longer located in Maryland Heights, MO like it was in 2011 when it was called stlouiscomputronics....working from his home now (according to the address)? His shop was really busy back then and turnaround time for my amp was 4 months. He replaced a resistor on a tube amp back then and although the amp worked, I'm assuming he didn't have the right value of resistor in stock so he piggybacked 2 resistors. Looked pretty amateurish, IMO. Wish I would have taken a pic at the time but I no longer have the amp. Not trying to rip on the guy, just sharing my experience.

    @michaeljhsda2 Thank you for your review of my company and I'm delighted that your amp worked fine. When we were in Maryland Heights, we were super-busy however most of our turnaround times never exceeded two weeks, However my wife died in 2012 from breast cancer and due to the fact that I was out with Lori at Siteman Cancer Center several times per week, some of my repairs during that time definitely had longer turnaround times, and I'm deeply sorry for that. I remember you as being very kind customer and I was thankful to perform your work.
    To add a bit of edification, it is very common that sometimes old values of resistors with specific wattages are no longer manufactured, and sometimes, we must wire two resistors in-series to equal the value of the original resistor. Respectfully, this is not amateurish: It is the Textbook method of achieving the goal.
    After parting from the Sound Room in 2014, I opened Precision Audio Labs and am now in the Saint Charles area.
    @Moose68Bash, Dearest Phillip, Many thanks for your kind words! You have blessed my shop and my life with your kindness and insight and I wish you and Lisa much happiness as you continue to listen with some of the best gear on Earth :smile: JJ
