Capacitor

I am not changing the value currently they have 0.33 uf was asking which brand to go with as there are 18 caps to change

@grannyring 
what is your thought on miflex KPCU caps

I like Vcap Odam much more than Miflex . Just pulled out Miflex and replaced with Odam in my amp. Much better after break in. Everything improved from bass to highs.  More depth, more inner detail…..you get it. 
Miflex are forward sounding and not as smooth and detailed as Odams. Odams are even better sounding than Jupiter copper in my experience, but I shared this already. 

I understand what you say, but then 18pcs of Odam 0.33uf 600VDC is some big money and miflex is less than half the price of Odam

I would advise to not change all your caps at once. Change maybe one or two pairs at a time and sit back and listen. If your sound goes in the wrong direction, you can alter your path. If you feel the sound is on the right path, you go ahead.

Each time you will hear an improvement, so you get to enjoy the improvement every time. 

Another benefit would be distributing your costs over time, so you can buy really good quality capacitors.
