Projects

Last week I started a new repair project: a 42” Philips TV. The power supply was obviously defect, but I ran into another problem as well…

Building a quality phono preamp is still one of the joys of the audio electronics enthusiast. This is my first take on a RIAA phono premap.

After watching The Signal Path for some I decided to treat myself to a classic 34401A 6½ digit multimeter.

This unit sold from 2012-2015 as the top-of-the line AV Network Receiver from Denon. I got my hands on a unit with power protection issues. Here’s the repair log the Denon AVR-4520.

Another lucky find: Rotel RB-970BX Power Amplifier with one defective channel. Let’s fix this!

The venerable Marantz PM80 Mk2. This unit was completely dead, but I was able to bring it back to life!

A classic 1989 Denon PMA 720a Integrated Amp that made a bang and wont’t turn on. Let’s solve this!

A Marantz SR5200 receiver with a non-working front-right channel. Let’s fix that!

Log of diagnosing and repairing a Denon PMA560 Stereo integrated amplifier.

A bench power supply is one of the essential tools of any electronics hobbyist.Although you can buy a such a unit for less that € 50, it’s way more fun to build one yourself.
