Have you compared it to a standard 7B80?? Sometimes the mods are obvious.

Subject: [TekScopes] Mod on horizontal plug-in 7B80
This is a tough one. I have a Tek Plug-In number 7B80. It is mod GB. I see no mention of this modification in the manuals. Anyone out there super knowledgeable who can give me the low down on mod GB?
