Upgrade capacitors in tube amplifier?

I have upgraded crossovers with very good results.  I now have a "very good" IMO chinese tube amplifier that can probably be improved with a couple of capacitor upgrades.  

I don't have a schematic, but I have a picture and I expect some of you knowledgeable folks can point me to/confirm the ones to change.  My thought is to change the two large silver ones first and then maybe the four smaller silver ones (on the circuit boards). 

Would probably replace with something like Jantzen Superior Z-Cap or comparable and go with a higher voltage if space permits.

Ok i can see the pairs of caps on the circuit boards,, 
Q: are they in power supply, or audio circuit? 
Got to know, Power circuit caps will not result in superior sonics, 
caps in audio circuit, like the 2 on the tube sockets,,will alter sonics. 
If you can geta  solid tech geek to advise, they I suggest go with Munorf Supreme EVO SGO, or EVO SGO.

Really there's not much to work with,,I'd say keep this amp, and later on look at a Cayin, which offers lots of caps/resistors you can swap out. 
On resistors  go with Takman Rey's.
hope that helps
