[Papa Tango Charly]

Hello, Here is my new schematic for C12 with a 6S6B-V i will probably use the original Apex 460 transformer + capsule C12 "CTS3 omni from taskar".sold buy Vami.
Tbone Black PSU.
Do you have any suggestions, or advises?
I was wondering if C4 1uf would be a good choice for the 6S6B-V
Thank you all for your cooperation!
