HP-46/81 Case, Power Supply

[Duane Hess]

Wish to ask some advice, just to ensure I don't get into a non-recoverable situation (i.e. things get damaged).

The service manual for the 46 & 81 seems to state the units use the same power supply. Certainly seems that way. I have all the parts for an 81 except for the case bottom, top and power supply. Pretty sure all the 81 parts work.

Own an extra 46 which is fully operable. Don't recall the values, but the 3 (4?) voltage test/check points in the 46 match the service manual. Before swapping the parts wanted to ask has anyone done this or is sure the power supply for the 2 units is the same?

Thanks!
