The nice thing about them is that they come with the PAC-5 and vacuum relay.
Performance isnt so efficient on 10M so its often easier to pull a tube and 
realign the input as for a LK-500. The difference in power wont be heard on 
any band unless you had 150-200W to drive the 3 tubes.

Prices usually start around $1500 for a nice one.

The NT version is a bit of a PITA and Ive converted many to Tune versions. 
Many of those can be found cheap with fried caps and tubes.

How common is the LK550?  What do they usually sell for?
