I’ve just repaired this lovely McIntosh Laboratories C220 preamplifier. This seemingly high-quality preamp fell victim to a growing problem with newer gear – modern Pb-free production processes.
The McIntosh C220 preamplifier is a hybrid tube/transistor based preamplifier, featuring a phono preamp and microprocessor control. It’s a well-made unit, though not like the McIntosh of old. The board is high-quality fibreglass and internal layout is clean and tidy, using nice parts.… Read more
I recently repaired and completely restored two stunning Accuphase M-60 monophonic power amplifiers. Read on to learn how these wonderful amplifiers were ruined by a local Perth electronics repairer, before they came to me.
The Accuphase M-60 is a monophonic power amplifier. It was top of the Accuphase range when introduced in 1975 and capable of driving almost anything.… Read more
I’ve just finished overhauling this absolutely incredible Sharp VZ-2000 linear-tracking record-playing boombox!
The Sharp VZ-2000 is one of the biggest and baddest boomboxes, from the golden era of boomboxes, the 80’s. This thing is seriously HUGE. I can hardly lift it and it took two hands to get it to this position for the photo-shoot.
More info can be found at the the Classic Boombox VZ-2000 page and this great page at the Laughing Squid.… Read more

You can read about my previous QL-F4 repair here. The JVC QL-F4 is a great direct-drive deck, perfect for someone stepping up from a belt-drive or lower tier DD.… Read more
I’ve just finished a repair on an amazing power amplifier – the Yamaha MX-1. You can skip to the video now, or read on for more details…
The Yamaha MX-1 was the best and most expensive amplifier in the Yamaha line-up for 1993. I truly had to wrestle this thing around the workshop, it’s so heavy for its size, it feels like it’s made of lead!… Read more
Lovely little unit, the Audiolab 8000Q preamplifier. Unfortunately, it’s let down by poor quality factory-fitted parts, particularly the capacitors. In this article, I repair this very nice pre-amp.
This Audiolab 8000Q preamplifier came to me with a fault which would see it sometimes take a long time to turn on. I’m talking a really long time – it would sometimes take up to 30 minutes to become operational after turn-on.… Read more
I recently repaired this Rogue Audio Sphinx hybrid valve / class-D integrated amplifier. The repair also reminded me of a valuable lesson in always checking the obvious!
The Rogue Audio Sphinx is a nicely made amplifier, hand-built in the USA which is a very good thing. The amplifier features an unusual topology, consisting of a tube preamplifier, solid state power supply, support circuitry and two Hypex class-D output amplifier modules.… Read more
