Re: How Many Scopes?
I can count 12 from my desk, there's about 10 or so (parts and fixer candidates) around the corner and maybe 4 or 5 5000 series in the other room. They include many 4xx series, a few 7000 mainframes

Hmmmm.... Let S = the number of 'scopes that one currently owns. Let D = the number of 'scopes that one acquires in the next 24 hour period that one buys one or more 'scopes. Let T = the number of

Re: 7S12 versus 7T11(A)/7S11 for general purpose sampling
Thanks, Albert. I will indeed put a 7T11 or 7T11A on my wishlist.? Yes, it can be a pain to get a signal to trigger on for the S-51 or S-53.? I am fortunate enough to have both. I figured the 7S12

7S12 versus 7T11(A)/7S11 for general purpose sampling
Hi Jim, Since your question is not related to the problems in the "7T11 horizontal memory" thread I opened this new topic for my answer. With the 7S12 you would also need an S-53 and an S-51 head for

Re: 7T11 horizontal memory
Say, since I have the 7S12 and 7S11, is there any reason to obtain a 7T11 or 7T11A?? Aside from the fact that it's another cool piece of Tek gear to own, I mean.? IOW, do I have a justification

Re: 7T11 horizontal memory

Yep, a colleague several decades ago told me if you ever work with audio tubes, try D.C. for the heater instead of A.C., you'll like it.? I never forgot that, although I have not worked with tubes
