Marshall changed to PCB's in 1973, prior to that they would have been turret boards. As far as I know no Marshall amps were ever built with tag strips.
I stand corrected. My mistake was in assuming that when McMurdo described his amp as "original", that he meant one of the early ones, which were of course built in the early 1960s. I should have checked the decades.

With regard to my mention of tag-strips, I really meant tag-boards similar to those used in Vox guitar amps and recalled that Barbara Craven claimed that Ken Bran populated "the component tag boards", even though he was Jim Marshall's Chief Service Engineer.

My excuse is that I was tired, which is a better one than some that I have heard recently.
