B1
Posted 29th January 2010 at 08:58 PM by Cro maniac
I finally gathered some will to deal with my Pass B1 project. I drawed the board in Protel and bought the components at Farnell almost 6 months ago, but never got time/mood/will to assemble it. Wednesday was my day off at work and I had nothing to do at home so I decided it is the Pass B1 day 
. I printed and made the boards, drilled the holes and lacquered them. Couple of hours later they were ready for soldering the components.
But hey, there is a bag full of 2SK170's that need to be matched prior to soldering ! I managed to get 3 matched pairs and I need only 2. Good enough
My version is the one with Salas regulator with R6 mod so I used the leftovers from matching in supply.
Now, everything is soldered and in place except input coupling 1uF caps and pot that I yet need to buy.
Now when it's nearly completed I don't sleep thinking how should the case for the preamp look like. I would really like to make it from wood.
