ac-dc adaptor?
The adaptor (5.5v, 500ma) for my Tungsten E seems to have burned out and I need a new one. I thought I'd buy one at RadioShack, but they don't have any 5.5v adaptors. Would a 6v, 800 ma adaptor be close enough?

the voltage part wouldn't worry me as much as the difference in the current.

You can think of the amperage rating on a power supply such as the one you're looking to purchase as the maximum "flow" of electricity it will provide. The voltage is effectively the "pressure" at which it is delivered. The power supply won't deliver more current (amps) than the device draws.
An aside: Some cheap desktop computer power supplies will not supply a consistent voltage if the current draw is too low (or, of course, too high), however.

That should be fine, just make sure that your new adaptor is a switching power supply (as opposed to a transformer-based one).

Switching adaptors are much lighter; here is an example from the RS website: http://www.radioshack.com/product.as...Fid=273%2D1691
