Dynaco PAS3 copy

When I had finished building my 6146B push pull amp I also wanted a stereo preamp. Although I tried many different ideas I always had problems with hum and finally I decided to build an exact copy of a Dynaco PAS3 preamp that was sold by a distributor in Sweden at that time. I bought the instruction manual for the PAS3 and me and my friend built ourselves two copies of the PAS3, we even made circuit boards after the photos of the circuit boards in the manual! My preamp worked very good with minimum hum and noise and I used it for many years until I started to think about the next project, Fully DC coupled preamp
