[Elecraft] K3: Speakers

[Edward R Cole]

David,

I checked my Power supply and it is marked 9vdc at 800ma.  Hard to 
know without opening one up whether a voltage regulator is used in 
the speaker itself.  If your substitute PS is 12v output probably no 
harm will result.  I find most of these wall cube PS rely on loading 
to bring them down to operating voltage.

I'm a little surprised to find it does not run on 12vdc, though.  For 
an item clearly designed for ham radio use it would seem logical to 
run on 12vdc supply.

I have considered all the devices I have running on these wall cubes 
and wondering if might eliminate the bunch by running off the station 
12v system (If they are compatible with 12v)?  Certainly some of 
these are switchers.

Glad that the end result was favorable, considering you bought the 
speaker on my suggestion.  I wonder if one buys direct from West 
Mountain whether they supply EU compatible PS cubes?  My guess you 
got a better deal buying local vs importing from the USA.
