What to do with broken McIntosh Pre-Amp


I inherited Klipsch Cornerhorns, a McIntosh MC2125 Amp, and a broken McIntosh MX 114 Pre-Amp.  Please forgive me for saying this, but I don't want to spend $800 or so for a pre-amp.  Is there a reasonably priced alternative out there?

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.
