TEST WITHOUT TUBES
#7
Hi Guys

Reforming caps should be done using a current limit of some sort. Some cap manufacturers suggest that the charge current should be limited to three times the nominal leakage current for the given capacitor, which means the current will be in the low-milliamp range t most, or even microamps. A high-value resistance will suffice inmost cases but this results in a reducing current a the cap charges up.

PLSS = power Limiting Safety Socket

The PLSS should always be used when testing amp that have unknown operating status, and for new builds and repairs, and for amps that have had a modification to their bis circuit. As our books Tonnes of Tone (TOT) and The Ultimate Tone (TUT) state, a variac does not limit power; rather, it limits voltage. If you have both a variac and the PLSS, place the variac first in line, then the PLSS. It probably makes no real difference to the test result, but this seems like the correct intuitive order.

Have fun
