CPP - 5 Power Supply

[BCA]

You'll know a CPP-5 when you try to lift it. Although it looks like a CPP-2, and is only 2" deeper, it weighs 129lb compared to the common CPP-2 at 95lb. The main difference is that the CPP-5 was meant to be used with 25 cycle per second power (the standard before our general conversion to 60cps) while the CPP-2 is used for 60cps power. Old electrical appliances like clocks sometimes have the sticker that indicates they were converted from 25 cps to use on newly introduced 60 cps. ........ Brian
