In this Part I look at the Amplifier designated as “No. 1”, a completed amplifier from AliExpress, I destroy the first amplifier and then test a second one (I had purchased 4 of them),
Part - 1 I have purchased four clones of the well-known JLH 69 Amplifier. I will test them all. One was a completed unit three were kits. I have an HP Distortion Analyzer that I intended to use but it failed when powered up, so I will be using a square wave generator and an oscilloscope for testing.
