I’ve just created a new page, dedicated to bad repairs. My aim is to raise awareness about the diabolical workmanship of certain ‘repairers’ who destroy hi-fi gear.
Unlike the rest of my site, my new Hi-Fi Repair Hall of Shame has one focus – to expose bad repairs. I’m especially interested in saving good people from tragedies like the ones you’ll see featured on this page.… Read more
Hi folks, this post is not related to audio in any way. Rather, it’s a summary of some recent problems I’ve had with my 2009 BMW R1200R motorcycle.
The BMW R1200R is a superb bike in every respect and a joy to ride and work on. I’ve owned more than 15 bikes over the years and this one is my pick in terms of being fun to ride, having gobs of torque, killer one finger brakes, almost no dive under braking, awesome handling, great range and fuel economy and the list goes on.… Read more
In the vinyl vs CD debate, I am often asked why vinyl sounds so good and why compact disc (CD) was created, if vinyl was a better medium in the first place? To put this another way – the question might be: “Vinyl vs CD – is vinyl higher resolution?”
This is not a simple question to answer, there is a great deal to consider.… Read more
I have been flat out with restorations and repairs. One of my recent jobs was to inspect and service a lovely example of a Krell KSA-150 Class A Power Amplifier.
You may have already watched my restoration video, where I completely refurbish one of these beasts. This video has actually generated a great deal of interest and I receive lots of queries in relation to my resto, and about the KSA-150.… Read more
This piece, about the Redgum RGi120 integrated amplifier, isn’t one I enjoyed writing. Redgum is an Australian brand and I really wanted to be able to write great things about the design and construction of this amplifier.
In the end, I couldn’t. I wrote this piece, considered not posting it, then hit go, only to pull it down after I was literally inundated with hits!… Read more
The infamous Sansui corrosive glue problem is one that affects many vintage hi-fi amplifiers and other equipment. Resolving issues caused by this glue is time-consuming, but essential.
You maybe familiar with the scenario – over time, your favourite Sansui (or other) amplifier starts to develop faults. Maybe it won’t come out of protection, or maybe a channel becomes intermittent.… Read more
A question I am commonly asked is “why do you bother lubricating the spindle bearing and why use synthetic oil.”
The answer to this is quite simple. Turntables are mechanic systems and as such require maintenance. When these turntables were designed, manufacturers often paid little attention to explaining this need, probably thinking that the deck would be superseded or out of use by the time this became a problem.… Read more
Capacitors – I am always on about capacitors and how important they are. I have literally thousands of the damn things in my parts inventory and I like to replace them, especially in certain types of circuits – but why?
To answer this we perhaps need to look first at what they do and how they are made.… Read more
Mike – should I spend a little on my old deck or just get rid of it and buy a new one? I get asked this all the time. Is there a simple answer? Well yes, usually there is.
There is nothing new in turntable design and much of the best turntable engineering and design was done back in the 70’s and 80’s.… Read more
