[Boatanchors] Tube QRP transmitter design

Hi,

First, I hope this isn't too "OT" for this list, it WILL be used with an 
SP-600.

I'm considering building a little "Glowbug" "QRP" CW transmitter, probably for 
40M.  May use plug in coils for different bands (like 30M etc).  I would like 
to use a 6AQ5 as the "final" as I have one, and would "like" to have a VFO if 
possible (stability may be a problem there?)  Otherwise, except for the RF 
chokes I have "most" of the needed parts, including a punched chassis, small 
power Xformer etc.

Can anyone here point me to an On-web source for various designs?  I have the
73 ARRL handbook which has a nice little 10W transmitter that could probably
be adapted to a 6AQ5 final with a (6C4?) triode oscillator (it uses a 6T9
Compactron which I DON'T have).

This rig would probably be used with my recently overhauled Hammarlund SP-600
"boatanchor" receiver.
