I switch to working topside for a bit. The surfaces are coated with a waxy substance to is easily scraped off or dissolved with acetone. Nicotine/tar glaze? Condensed wax and from hot components?
The metal underneath is very clean for the most part.
I removed the three caps next to the power supply and cleaned. I'll be using two CE Manufacturing twist-loc caps.
The middle cap is a smaller diameter type mounted on a phenolic insulator.
I'll just hide a new cap inside the original cardboard sleeve.
