My Mission Cyrus One amplifier is great, but it doesn’t have a headphone socket. I now use an external headphone amplifier, driven from the tape out RCA sockets. Before I made that investment I got great results from this modified speaker switch box.
Book learning about Valve or Tube circuits
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”
Denon UD-M30 CD Receiver volume problem fix
The Denon UD M30 is a rightly popular mini system which delivers excellent sound from a unit the size of a shoe box.

Valve Headphone Amplifier
Vinyl after dark denied because my Mission Cyrus amplifier has no headphone output. I need something to connect to the tape out RCA sockets. I considered DIY, but it would have cost as much as a bought one to make anything that looked half decent. Research showed that a valve amp could be had for the same price as a solid state one. So, for about £30, I got me this.
