From: larya on 6 Apr 2010 16:50 Greetings... Recently a ham friend of mine gave me an old oscilloscope.. By the looks of it, I estimate it to have been build during the 40's... Grosfield made in England..type TA.. Does anyone know of this scope?.. I would like to get the schematic diagram...There are two tubes missing.. They are located on the top and by the position of their tube sockets are positioned over the CRT... Larry ve3fxq
