[Elecraft] KX3 (or, K3) 2-meter solid-state amplifier

[Phil Hystad]

Kevin,

Yes, I know of W6PQL.  In fact, on my first version of the message I posted, I made a few comments about the 80-watt 2-meter amp.  But, I thought that would be too much in one message so I did not include it.

I was planning to build the W6PQL 80-watt amp and was already to order the commercial PCB fitted out with the SMT parts which is still a good deal.  But, and this was the thing that stopped me, I could not find a descent utility cabinet for the amp.  W6PQL lists instructions and templates for making your own but I have tried that before.  Without a bending brake it gets really sloppy in forming the box.  I can cut the right gauge aluminum no problem.  I even looked into buying those little corner bracket things that Elecraft uses in their kits for joining two sides at 90-degrees.  But, it would have cost almost $50 for those alone (Elecraft charges pretty pennies, lots of them, for those parts).

I am still on a half-way hunt for a good box.  I have even scoured the local ham-fests this year looking for something that might work well without too much trouble — didn’t find anything.  The boxes that are offered by various electronic parts suppliers just don’t seem suitable — they would be a very last resort.
