While it looks like a toss up for the W6PO design and the K1AGB, with the PA3CSG coming in last but interesting. Now to start building....Unless someone wants to Trade? Brand New in Box 3cx1500A7/8877 Date code 6/06 Will trade for a two meter amp either design, (W6PO) or K1agb), Just throwing this out if anyone is interested. 73 Bruce N9BX
