What to do with broken McIntosh Pre-Amp

Everyone knows "someone special" to fix your McIntosh MX 114. So? I do, too. He has a video series which runs to the hundreds of videos... and can fix ANYTHING. His name is Paul Carlson, of Mr. Carlson's Lab on YouTube. He will do WHATEVER needs to be done and owns more test equipment than some laboratories, much of which he has buffed. Listen to him, he knows all, but his usual money stream is fixing switching mode power supplies for CNC machines. His contact info is on his site. From the US (as he is in British Columbia), call 206 259-9312 from 8:30 am to 4:30 pm AT HIS LOCATION in Canada. 

If you choose not to get it fixed.  This is an alternative.

Thank you all for your recommendations.  I’m going to try that $50.00 Chase controller for now and send out the pre-amp for repair later.
