Build-up – Preamp
by Russ Knize on Feb.03, 2009, under
The preamplifier and driver section. The four tubes on the left are the mu-followers and the two on the right are the cathode-followers. Some old RCA cables were butchered so that I could test each of the sections. I ended up using it this way for a few months because it was the only preamp I have. Below the large output capacitors, you can see the ductwork for the fan. A small amount of air is directed under the caps to the components behind the tubes. The rest passes under the torroidal transformer to the power supplies.
