Re: [TenTec] IDing version of 525 Argosy w/o serial nbr?

[John Graves <jh.graves@verizon.net>]

Dave,

I have S/N 525 00042.  I am guessing it was from one of the first few 
runs but have never called to check that. My S/N is stuck vertically on 
the back between the cooling fin panel and the phono jacks.  My RF & 
IF/AF boards are plain numbers, no A or B versions.  In the FWIW dept. I 
have a 8122 filter on the RF board and 219 on the if Board.  Are there 
any stamps on hte chassis that may help dating?
Don't know if that helps but I am happy to answer any other questions 
you might have.
