Here's a good idea of what's all over the machine. What seem to look like more modern carbon resistors, small axial lytics, metal can transistors with a red/yellow/blue color coding scheme, relatively large glass diodes and those yellow capacitors. They are not wax dipped. It's some other hard material that isn't plastic. Anyone seen this before?
These caps are very reliable and sell for good money on Ebay. Keep them in every case!
