[Boatanchors] HT-40 Final Toob

[Daniel Wright]

Greetings!

I am working on a couple of HT40s and could use one or two 6DQ5s, the 
final tube in the xmtr.
My questions are:
Is there a good and cheap (ha!) place to buy them?
OR...is there a mod or tube substitution that can be made instead of the 
6DQ5?
I have a basketfull of 6DQ6s, but I can't find any info that they are a 
good substitution.
Any help greatly appreciated!
