Pioneer PL-530 Direct-Drive Turntable Service & Repair

I recently overhauled this lovely old Pioneer PL-530 direct-drive turntable. Let’s take a closer look. This model is not especially common, but it has a great vintage look and some great features that I think make it one to keep an eye out for. Pioneer made some great belt-drive and direct-drive decks and many of […]

Denon SL-7D Direct-Drive Turntable Service & Repair

I’ve just finished repairing and servicing a lovely old deck that one doesn’t often see – a Denon SL-7D direct-drive turntable. My customer received the run-around from several technicians and wanted me to have a look to see if I could get her going again. This Denon SL-7D came fitted with a gorgeous old AKG P25MD moving iron

A friend of mine recently asked me to take a look at her Ericsson Ericofon, commonly known as the Ericsson ‘Cobra’ phone, just the other day. I was away from home and so I had no test and measurement gear, no soldering iron, no tools, but we made do with a few things she had

Marantz SM-80 Amplifier Repair & Restoration

In this second article on the Marantz SC-80 and SM-80, we look at the SM-80 power amplifier and a tricky repair and restoration.

Marantz SC-80 Preamplifier Repair & Restoration

I’ve recently restored an immaculate Marantz SC-80/SM-80 pre/power combo. In this article, I look at the SC-80 preamplifier. The Marantz SC-80, and its partner, the matching Marantz SM-80, are quality mid-range separates hailing from around 1990. They are unremarkable in terms of circuit layout and construction, but well made and thoughtfully laid out, making service

BMW R1200R Motorcycle Problems

In this article, I discuss problems with my 2009 BMW R1200R motorcycle. Warning: the list is extensive, but the biggest problem isn’t the bike… Updated: 2023, with a twist! This isn’t an article I enjoyed writing back in 2015, or updating in 2017 before I sold the bike, but it’s the sort of article that

JVC QL-F4 DD Turntable Repair & Service

I recently worked on a very cool and lovely old JVC QL-F4 direct-drive, fully automatic turntable. Let’s take a look inside. The JVC QL-F4 is a mid-range deck from the once-great JVC. Even in the late ’70s and early ’80s, JVC was not known for its hi-fi separates. This is a shame because this series
