did you say that just to provoke me?
you can take my 1740's when you pry them from my cold dead hands.
ps ok....i would not say that around swmbo.....since she would not see a down side to the deal.

Good work, yes those are properly engineered and should last many years yet, love the analogue meters as well, makes it much easier to set the parameters. I think with digital we all strive to be as near to perfect as it's possible to get, even though it's not critical.

Hahahaha. That's quite a collection there. I did previously own a 1740A and did rather like it for ref ;)
Stuffed another bench power supply across the hole where the blown up zener was and guess what? Bloody works perfectly. Now mystery manual misprint makes it difficult to find out what the hell variety of zener this is. It's currently just a shorted zener with an HP part number is 1902-0650 which is apparently a 1N4353B. Hmm suspicious. Turns out after doing some googling it should read 1N5343B and the pairs of digits are transposed! :palm: technical author failure. Fortunately RS stock for £2.27 inc delivery for 5. Be here Monday :D

I actually love using my 1740A, feels nice to the touch and is beautifully liad out. It has some very nice touches internally and some crap ones as well. The rotary switches are both a clever design and bad at the same time, clever but poorly executed as they wobble all over the place when operated putting flexing action onto the boards that they plug into. That said, once you know how, the whole scope can be quickly dismantled for servicing.
Major downsides are the hybrids and their sheer size and weight and that a factor that making me examine the longevity of mine in my collection.

yep. they are easy to disassemble and that is a big plus. but those post pin headers that connect the assemblies have gotten to be a source of annoyance. unless you enjoy wigglin' boards every now and then to eliminate a jumping trace .
can't see a flaw in your logic. but TEA is not logical. some things you like just because you like 'em.
