A queston regarding TAB V74 0db pre-amp

Hello all,
I've a question regarding the TAB V74. I own 2 of them with S/N 1277 and 4360. The one with the lower S/N is -11db quiter as the one with the higher S/N. I use this diagram but as it is a very early one I would like to ask If somebody knews about later modifications. The Braunbuch is not available at the net I'm afraid. Before I will connect my scope and start measuring I would like to ask for some ideas.

Thanks alot

Excellent, that´s what I was looking for :grin: . Indeed there are some more modifications but this will bring me much closer to the answer.
vielen Dank und viele Grüße in die Bundeshauptstadt
