Great scope porn
very nice collection. You have the same scope mobile as my 547. If i had the space the 556 would be on top of my list. I have a fairchild 777, that is about the same size, all transistors, same time area, 100 MHz, 4 plugins but 2 defect, no manual, psu problems and the dual beam CRT turned out to be at its end.
That is indeed the original sun protection. It came with a 535A.
I have a HP VNA ( 8407 or 8704 alway mix them up) with a long persistence white trace and a Tek XY monitor with orange screen and orange long persistance Phosfor and a vector monitor with dark green phosfor.
I never seen the blue traces, real cool. I once seen pictures if the LCD shutter thing in front of a Tek scope. That gave several collored traces, looked awsum.
Do you know if there was a red gratitude option for the 547 like your 533 has and my 535A. That was the thing i liked the most on my 535A. Would love to have it on my 547
