Krell KSA-150 Class-A Power Amplifier Restoration

A couple of years back I performed a comprehensive tear-down, overhaul and upgrade of my gorgeous Krell KSA-150 power amplifier. I made a video of it, which you are most welcome to check out.

There’s not much you can buy that can touch the performance of a class A amplifier of this quality – let’s face it – the Krell KSA-150 was ten grand – in the early 90’s!… Read more

Technics SL-Q5 Turntable – Linear Tracking on the Cheap!

I recently serviced a customer’s Technics SL-Q5 direct-drive, linear-tracking turntable. This is a mid-range linear-tracking deck from the 1980s and well worth keeping an eye out for.

The deck is typical Technics in being well designed, well made and easy to service. The issue with this deck, and many others like it, is that it has not been serviced and has eventually displayed a fault that meant it could no longer play records.… Read more

Technics SL-1300 Direct Drive Turntable Service

The Technics SL-1300 is a great example of what I am talking about when I refer to classic direct drive decks from the golden era of excellence in the engineering and manufacture of turntables.

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

Servicing the Technics SL-1200 Direct Drive Turntable

The Technics SL-1200 direct drive turntable, in its various iterations, will be well known to most vinyl lovers these days. They have become almost legendary for different reasons – DJs love them for their fast startup and solid build; home users love them for their engineering and audio bang for the buck.

Make no mistake – the SL-1200 is no audio weapon in the big picture – it is never going to scare an SP-10 or L-07D.… Read more

Servicing Your Turntable Will Improve Its Performance

Clients will often ask “Mike, does my deck really need a service?” My answer is always the same and based purely on my experience – there are very few situations where a service won’t make a really noticeable improvement in operational and sonic performance.

I usually reply with “Have you ever had it serviced?”, “Has the bearing oil ever been changed?” and “Has your cartridge ever been properly aligned?” You can probably imagine that in most cases the answers to these questions are no. 

Turntables are complex mechanical systems that DO need regular maintenance.… Read more
