Ive built a few SLO amps and even though they sound very good I still feel you just cannot beat a good marshall or fender amp!
The classics just never die!!!

No, but I will tell you what I put into a Brown Tolex 6G2 Princeton amp. The network went in between the first stage coupling cap and the 1M Vol. pot. Using the component #'s from your diagram, R1 & R2 = 220K, C1= 500pF, C2=.0033uF. You can plug these values into a circuit simulator to see the effects of changing the components or just listen as you make changes in the amp.

I forgot to mention - Regarding the 6G2 Princeton: I also removed the NFB loop and added a 22uF cap across the second stage cathode resistor to bring back the lost gain from the network and increase low frequencies a bit.

Have a look at this for an explanation on T filters:
