Fender Champion 600 Tube Mod Recommendations

I found this great site that also has a very specific tube modding process recommendation all spelled out.  He also talks about the exact tubes he would put in right away.  Well, my new Fender Champ 600 has not arrived yet-- I expect it Friday-- but when it does I plan to play it first and then decide. 



Akavalve has posted the following blog entree:

Addionally, I would like to offer this link for a recommended set of JJ tubes, presumably for an upgrade in overall sound and earlier breakup or distortion.

I will try these out first if I do change out the tubes.  Remember, mine is used but mint and has had the capacitor tone stack replaced and a new Weber Alnico 6 inch speaker installed.  Adding the tubes will just about finish the job!!! 

Can't wait to review the amp.  -- Guitar Man
