[Boatanchors] Amps for QRP rigs

[DW Holtman]

Hello,

Thanks to everyone for some of the great ideas. Jim, W5JO suggested a 60's 
ARRL handbook. I have a 1966 edition. It has two suitable amps in it, one 
uses a pair of 6146Bs and the other uses an 811-A.  I will have to look both 
of them over very carefully and decide which has parts the most available. 
But, they both look doable. I think I already have the iron for the power 
supplies, will still need most of the rest. I have a pair of 6146W and a 
pair of 6146 plain tubes, but no 811-a.

This should make a great project, that is not too complicated and I "think" 
I can tackle.

Any suggestions on which way to go, as far as tubes go from experienced 
builders would be greatly appreciated.

Best,
DW Holtman
