[R-390] Isolation Transformer

[Scott, Barry (Clyde B)]

List,

(Sorry about the previous message.  I'm not sure what I did, but it was sent
prematurely).

I'm looking to buy an isolation transformer for various BA work and found
these.

Particularly, I'm looking at these two items:

(TP)64196-173022,  new - as removed from new, unused equipment.
(TP)6634  New in the box.

Of these, does anyone have any recommendations for either?  I assume either
is overly sufficient to power a two or three R390s, but not sure about other
considerations.

Any suggestions?

Thanks,
