[Elecraft] Power Supply?

[Andrew Moore]

K7PEH> You would need a cooling fan in their for a 20 to 25 amp supply and I
don't think the P3 is set up to handle a fan.

My RS-20M doesn't have or need a cooling fan (though that's in part due to
its venting and heat sink, so that needs to be carried over to the P3
enclousre).  I'm going to see if I can migrate it to the P3 (which itself
probably doesn't generate a lot of heat).  If it needs one, fans are small
and can sit right on top of the case, fed with 12 V from the supply that
will now reside inside.

AC7AC> And much of that space in the P3 is reserved for P3 add-ons that are
in development.

I expect I'll be so happy when my bare bones P3 arrives that I'll live with
it as-is for a while.  If I'm tempted to fill out the inside with add-ons,
I'll remove the supply at that time and figure out Plan B.

AC7AC> I rather like the idea of an external power supply. It doesn't need
to occupy table-top space; mine sits on a box under the desk.

Same here - but I'd like it more if it matched the P3 enclosure.  And now it
might... This may be too ambitious but I'll give it a shot and won't be too
proud to say "you can say you told me so" if I fail.  If it's too much of a
stretch to fit a 20 A supply in there, I'll use a supply of less than 20 A,
and settle for running less than 100 watts from the K3.  When I get a KPA500
sometime in the (distant?) future, I'm sure the stepped-down K3 would still
have plenty drive to run the amp at a level acceptable for my needs.

Really wish I could just buy a blank P3 enclosure and save all the trouble.
