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.
Technically speaking, the BAT VK-500 MOSFET amplifier is an amazing design. It uses all MOSFET devices in the driver and output stages. It features 24 N-channel MOSFET devices in the output stage, avoiding the inherent complementary pair mis-matching problem.… Read more
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.
The Yamaha CA-710 had blown one channel. One of the original output devices, a Sanken 2SA745, had a collector to base short and it had taken out one of the driver transistors.… Read more

I was quite surprised by the weight and overall build quality of this lovely JVC direct-drive turntable. The JL-F45 is a fully automatic direct-drive deck. For those who don’t know, fully automatic means that the tonearm is controlled by the turntable, not by you.… Read more
The Pioneer PL-A35 is one of those rare belt-driven Japanese decks that you don’t see very often. I’ve repaired a number of such unusual decks in the last 12 months or so, but this is definitely one of the nicest and in some ways, the most unusual.
According to Pioneer: “The PL-A35 combines studio-quality performance with the operational ease of a fully automatic!… Read more
The Technics SL-23 is a common and very cool belt-drive deck from the late 70’s. I highly recommend the SL-23, ahead of early Rega, Dual and Thorens decks, for someone wanting a first ‘proper’ turntable.
Technics is of course best known for the SL-1200 range of direct-drive turntables, but they made a range of machines, at varying price-points.… Read more
