BAT VK-500 MOSFET Monster Amplifier Repair

A regular customer of mine had an issue with one of the binding posts of his amazing Balanced Audio Technology VK-500 MOSFET amplifier. I fixed it for him, read about the repair below.

Yamaha CA-610 and CA-710 Integrated Amplifier Service & Repair

Recently, two friends with lovely vintage Yamaha CA-610 and CA-710 integrated amplifiers sought my assistance to have them repaired. One was dead, the other was not working well.
