Hi branching out

Hi, wanting to expand my tube amplifier knowledge - previously worked with simple 1950s phonograph amplifiers.

Now i have inherited "works in progress" from estate sales. Unfortunately no schematics to go with them so i thought i'd try here. looking forward to reviewing the accumulated knowledge available here. Thanks Rich
