Hello guys!
Some pictures from my latest project.
I needed a preamp with some gain to drive my ZV9. The B1 I used had not the juice to drive the amp to full output with some programmaterial.
I wanted a solid state amp and I had already made the powersupplie so the +-15V was in place. I tryed some other preampideas from the internet but I was not fully satisfied. Then I got the idea to do something F5-like. And it worked out rather well I think. Please give me some feedback. More pictures if you want.
Merry christmas from Sweden, Abrandt

The cascod is mostly because I would try to do it and maybe to get a little less distortion. You could absoluteley make a version without them. Your question about the reference voltage, I don't understand. I have to get fixed voltage at about 5 Volt's at the bases. I could done that without the zeners maybe but ??
