Join me for my longest video yet, as I repair and upgrade a broken Musical Fidelity Tri-Vista 21 Tube DAC.
Follow along as I describe finding and repairing the faults, upgrading and then testing this wonderful Musical Fidelity Tri-Vista 21 Tube DAC. In the end, I was able to achieve just 0.001% THD + noise from this baby, a superb result!… Read more

Yes, this thing is officially silly, 170 watts per channel of oval capacitor madness! In this video, I basically run through the service process from first unveiling the beast, to final testing.… Read more

In the first part of the video, I open up the Marantz for the first time and discover the terrible state she is in.… Read more

More photos and details of the Marantz PM-8 restoration soon.… Read more
