I love the 6DQ5, best SSB final tube made IMHO.   My GSB-1 and Swan 240 
amaze me with what a single DQ5 final will do - 150 watts PEP or more.   
Someone has posted a nice little class AB1 linear here:

Unfortunately, the 6DQ5 won't do grounded-grid since the suppressor grid 
is internally connected to the cathode.
