Accuphase M-60 Power Amplifiers Repair & Restoration

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

Sharp VZ-2000 Record-Playing Boombox Restoration

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

Sansui BA-F1 Power Amplifier Restoration Update

I’ve now finished restoring a lovely Sansui BA-F1 DC power amplifier. The Sansui BA-F1 is another beast of an amplifier from the golden era of hi-fi.

This Sansui BA-F1 has had a hard life, but will be good as new, once I’ve finished this restoration. I’m replacing all board-mounted capacitors, along with a few semiconductors. I am also cleaning and tidying up wiring and board goofs made by whoever repaired this previously.… Read more

Classic Quad 405-2 Power Amplifier Restoration

I recently acquired a classic Quad 405-2 power amplifier. She sounded fantastic before overhaul, but read on to see how she sounded after!

For some extra reading, check out my Quad 405-2 review and Quad 405 refresh.

The Quad 405-2 is revered by many, even 40 years after its release. It’s not hard to hear how the 405-2 does an amazing job of getting out of the way and just playing the music.… Read more

Marantz PM-8 Esotec Amplifier Repair & Restoration

I’ve been very busy repairing and restoring this stunning Marantz PM-8 integrated amplifier.

The Marantz PM-8 has to be one of the best integrated amplifiers from the golden era. These things are monsters, massively powerful and massively heavy. They are also massively complex to work on and this one had a massive fault!

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

Technics SL-120 Direct-Drive Turntable Restoration

I was recently asked to undertake the restoration of a lovely old Technics SL-120 direct-drive turntable. The SL-120 was basically an SL-1200, without a tonearm. Owners often chose to fit an SME 3009, as was the case with this old deck. This one though, had seen better days…

The Technics SL-120 is a quality direct-drive deck, featuring an ultra-low speed brushless DC motor.… Read more

Luxman C-5000A Preamplifier Repair & Restoration

A customer recently asked me to restore a gorgeous Luxman M-4000A power amplifier and a matching Luxman C-5000A preamplifier. In this article, we run through the C-5000A restoration.

You can read about my M-4000A restoration here. This post looks at the C-5000A, a rare and beautifully built preamplifier, from the somewhat enigmatic manufacturer, Luxman.

No Service Data

The Luxman C-5000A is so rare in fact that, despite searches and contact with the Luxman Yahoo group and the Luxman Vintage Audio website, there are no service manuals available for the ‘A’ series models.… Read more

ERA Mk 6 Belt-Drive Turntable Repair & Restoration

I recently was asked by a customer to restore her partner’s lovely old French ERA Mk 6 belt-drive turntable, as a surprise birthday gift. I was very happy to assist of course, and it gave me a wonderful opportunity to work on a deck I had never seen before. 

The ERA Mk 6 is a belt-driven deck from the early seventies.… Read more

Krell KSA-200S Class-A Amplifier Repair and Restoration

I am about to embark on a Krell KSA-200S Class-A Amplifier Repair and Restoration, in this case for a very good friend of mine.   

As many of you will know, the Krell KSA-200S is a beast of an amplifier, up there with the very best products Krell ever made. It is almost unliftable by one person, being hewn from solid slabs of steel and aluminium.… Read more

Marantz SM-80 Amplifier Repair & Restoration

In this second of two articles on the Marantz SC-80 preamplifier and SM-80 power amplifier, we look at the SM-80 power amplifier. Specifically I detail the work required to restore this amplifier back to full working condition. The earlier article looks at work done to matching Marantz SC-80 preamplifier.

The Marantz SM-80 stereo power amplifier is a reasonably powerful, well-made, mid-range consumer amplifier from around 1990.… Read more
