I've been tackling this set over the past few weeks. Here it is up on the workbench for a closer look. Despite the filth, it's all there and appears to be in pretty good condition.
Rather that take my usual shotgun approach, I decided to have a little fun and see how far I could get without removing any circuit boards.
First, the power supply. Although it has a power transformer, it has a voltage double for the B+. I could see the main filter caps were leaking and crusty so they had to go before attempting a power up.
Here they are along with some new diodes installed on the existing terminal strip. Also did a little vacuuming and pulled the HV cover off.
