I recently bought three cartridges and head shells for just £3. While I will probably use the head shells, the cartridges are not going to be allowed near a decent record. Let’s take one apart and see what’s inside. Continue reading “Phono Cartridge. What’s inside?”
I’ve had this bass amp for years. It’s only been gigged once, I mainly use it as a practice amp. It has a great sound and a very useful built in compressor. I bought it 1/2 price from a music shop that was closing down.

University taught me most of what I needed to know about the theory of electronics, but not a jot about valves. They had been dropped from the curriculum in the 1970’s in favour of these new integrated circuit things!
Having acquired a Quad Valve system in need of attention I had to learn about Valves. Continue reading “Book learning about Valve or Tube circuits”
My Sony WM-EX662 Cassette Walkman just doesn’t seem to work as well as my similar WM-EX550.
It has had a belt change, but still suffers from flutter. Recently it has also developed problems with the controls. This turned out to be complex to understand, but easily fixed. Continue reading “Sony Walkman WM-EX662 benefits from Aiwa parts”
