McIntosh MX110 And Dynaco ST-70. Vintage Tube Preamp Tuner Amplifier Repair Restoration Testing.

This video shows the repair and restoration of both a McIntosh MX110 Vacuum Tube Preamplifier/Tuner and a Dynaco ST-70 Vacuum Tube Amplifier. This all vacuum tube McIntosh MX-110 is a wonderful sounding Preamp/Tuner. All of the coupling capacitors were replaced as well as the electrolytic capacitors. The Dynaco ST-70 is also a really good sounding vacuum tube power amplifier. When I purchased the ST-70 it was non-functioning. After restoring both the MX-110 and the ST-70 they truly make beautiful music together.
