1st full tube amp Oldchen EL34

Picked this up inexpensively to try on my Klipsch Quartets or Chorus 1s. Do not know much about vacuum tubes. I have recapped many ss amps but this is foreign to me. Seeking any and all advice on various nuances. 
 

I have a significant amount of silver coated copper wire encased in PTFE, was considering replacing the wiring. Have not opened it up yet so more to come based on what I find. Thanks for any feedback.
