About flim capacitor

Hello,

I'm going to tweak up a tube preamplifer. There are two Sovtek 12AX7 tubes. And there are two brown capacitors located near each tube. These caps are my problem. The label of two capacitors near the 12AX7 tubes say "0.22K 250S" What does the label mean? Is it "0.22uF 10% 250VDC" ?

I don't have specific pictures of the caps I'm talking about. However, I have a picture of a brown capacitor that looks similar to the one in my amp. Thank a lot.

You right, this is 0.22uF 10% 250VDC capacitor, MKS type (letter "S" after 250).

Cap on picture - 4.7uF 10% MKS 100V.
"B7" is probably lot code, or package code or something else.

Thank you so much...Vidalgo

Is it possible for the cap used for coupling? If yes, which types should I consider for tweaking up?

Thank a lot.
