That link has some weird special characters stuck on the end of it. Not sure 
how that happened. This link works 
https://elecraft-kx.groups.io/g/main/message/9486 and is the link in the

[Elecraft] KPA500 for sale; delivery at HamVention

2023-05-17 Thread Rus Healy 
I am the second owner of a very nice KPA500. I have recently replaced the
finals. The amplifier puts out full power on all bands. I am selling it to
fund some microwave EME purchases.

The amp is wired for 240 V ac but it is easily changed to 120 V without
opening the covers. (New ceramic fuses of the correct rating would be
required.)

Includes power cord and factory packaging. I would prefer to deliver in
person this week at HamVention (Thursday evening through early Sunday), but
I could ship it next week as well.

Price is $2400 firm for in-person delivery, or $2400 plus actual shipping
and insurance costs (domestic US only) for shipping.

PayPal (F&F) or cash. Message me directly at [k2ua at arrl dot net], not to
the list. Thanks.

--73, Rus, K2UA
