Guys,

We are working on a nice BC224D on the USS Wisconsin. There is a 41 tube we need to check and it is being held in a ring type band with what appears to be pins. I looked under the chassis to see if they were screwed but didn't see anything. I know this has to be simple since tubes need to be checked from time to time..

Please any information would be appreciated...

Thanks In Advance...
