10A dual-meter dual-range variac in museum condition
In case you are not an expert, a DUAL RANGE Variac is ideal for testing low-current things like tube or solid-state preamps, AND high-current things like power amplifiers, guitar amps, and, especially, tube amps that have been sitting a long time. You can bring the voltage up SLOWLY and see if the item is drawing excess current.
Having a dual-range meter (0-2 and 0-10 Amps) means that you can get accurate current readings. Dual fuses is even MORE important. This way you can protect your item under test from catastrophic failure in case some part is defective in it.
I looked carefully, and I see no significant scratches or other blemishes to report.
