After many years in storage and on display I decided to took these amplifiers out of storage and
fire them up in order to use them.
First I started with the BA 303:
Set the bias of the 6550 valves and put it on the test bench to test some of its audio parameters.
Previously all the valves were tested on an AVO valve tester regarding the Ia and Gm measurements.
Here is a link of some previous pictures of the amplifiers:

I will keep you posted regarding the progress on this project as I want to do
"interesting things" with these three amplifiers.
