TEST WITHOUT TUBES

[makinrose]

I assume by a PLSS you mean light bulb limiter? Typically when I do this I would only use it not the variac. Others might weigh in differently on this but I'm not a believer that filter caps should be re-formed using Variac. If you do use a Variac should it be used with an isolation transformer for safety.

Depending on how long the amps have been sitting you might have to plan on re-capping them. Caps don't last long if they are not charged regularly.
