[Amps] DC Blocking Capacitor

[Patrick EGLOFF]

While we are talking about blocking caps.
I'm collecting parts to build my 2m amplfier using a 4CX1500B.

I have 2 sort op caps and would like to know if they are OK for use on 
2m ? I have 2 of each.
First one is marked and should be OK, but i don't know if usable on 2m.
Second one has no marking, it's doorknob type and measured to be a 50 
pF. I would put 2 in parallel to have more current handling capabilities.

Please look at pictures here :
