Your Editor reflects on 14 issues, 2 books and 7 years and concludes It’s been a great adventure!

After several theoretical installments, Giovanni Stochino  puts his money where his mouth is and gives us an Audio power amplifier with BEF error correction delivers 150W into 8Ω at 0.0004% THD

Our friend Rudolf Moers is back with An investigation of the screen grid tap - a search for the hidden arguments.

Ian Hegglun is back with another out-of-the-box power amp design as only he can do, with a Current driven Output-stage class AB power amplifier.

John Vanderkooy and Richard Mann joined forces to come up with An Open-Source Electroacoustic Measurement System: Part 1: Theory, Practicalities & Acoustic Examples; Part 2: Sound Card Setup, System Characterization and a few more Examples.
