Great piece of de facto standard equipment for variable isolation transformers / varia
Sencore PR57 is the standard that others are measured against. Had 1 in the early 70s, sold it off to one of my employees. Bought 12 when working at Sony and now 30 years later buying a used one. Don't know why Sencore stopped making this but they are now focused on communication equipmentVerified purchase: YesCondition: Pre-owned
