With no more information than that, I'd start with a 6EA8 (to replace the 6U8 in V2) and a couple of 6BE6 to swap out for V3, V4 and/or V7.

It's most likely one of them. If not, then further troubleshooting will be required.

For awhile now, my Drake 2B received CW with unstable frequency for about 30 minutes after being turned on. The received note is unstable. Any ideas where to start troubleshooting this. Unfortunately, after warming up everything is fine.
