Hi

I've got an old Tek scope (547), and still use it. It has plug-in =
modules for the vertical amplifier. Normally I have a "Type CA plug-in" =
installed, dual-trace, about 20MHz BW. When searching the attic, I found =
another one of these modules (Type 81 plug-in adaptor) with a front =
label (Type 53/54C plug-in unit). It looks the same as the Type CA, but =
mustn't it be some difference ?

Is anyone on the list familiar with those old Tek scopes, or can you =
point me to a good info source ?

Regards
