mypicturedlifea photographic record of my life


I bought this second hand and found myself distinctly underwhelmed with the sound quality.

I decided to take a look inside, and reverse engineer it.

Imagine my disappointment when I discovered that the claims of "Uni-junction FET Preamplifier - Single ended class A" on the rear were untrue.

It transpired that the only FET device in the unit was the Op amp for the DC servo.
