I see two "twist prong" (aluminum can style) electrolytic capacitors in the rear left corner of the picture. They will need to be replaced as part of the capkit. These style capacitors are usually part of the high voltage (450 to 500 volts) B+ power supply and are often the first to fail and take out a power transformer.
If there is a tube "missing" it's probably the tube which controls the Automatic Volume Control circuit. The amp will run without it and many operators pulled that tube out because of "low volume" complaints. The purpose of the tube was to regulate the volume between different qualities of records. Back in those days record recording standards were poor/non existant.
Both vendors stated the electrolytic can caps are not available. They were last made in 1985 according to Bickers.
A mod is now recommended, which I will try to document. It was stated the cans will be unwired, and can remain up top purely for aesthetics.
