Hi Barry,
Very good - I'll take closer look at the 465B - easier to get parts as well, I believe.
Thanks and kind regards,John

I have several scopes including a 453 and a 465B.? I like both but if it came down to only keeping one, I'd keep the 465B.
Thanks,

Subject: Re: [TekScopes] Opinion on 'scope selection
Speaking as a collector, with a collection that started in 2016 with a 475 (I'm
not counting a forgettable modern DSO) and has since grown to twenty
oscilloscopes and curve tracers, I suggest attempting to obtain all of them. ?
But assuming only one...
It depends on you, what you want do to with a 'scope, and what you're
comfortable maintaining.
For easy repairability, totally manual operation and relatively low bandwidth
(maximum 50mhz) I'd go with the 453.
For maximum bandwidth and some measurement capabilities, but perhaps more
difficult repair, go with the 2465A. The 2445, 2465 and 2445B are essentially
equivalent but lower bandwidth. The 2465A is 400mhz.
I know nothing about the THS730A. That's a newer, portable digital 'scope.
Probably the most in-build automated capability, but perhaps most difficult to
do-it-yourself repair if it needs it, and not everyone likes driving digital
'scopes.
The others kind of fall in between, I guess. The 2236 has a built-in counter and
digital multimeter, which is nifty. The 2246 is analog with some measurement
features. The 465B is like an updated 453.
Tough choice!

Subject: [TekScopes] Opinion on 'scope selection
An opinion please.? A friend is offing me a choice of one of his Tek scopes:
453, 465B, 2236, 2246, 2445, 2445B, 2465, 2465A, and a THS730A.? His plan is to
sell-off the inventory¡he has a lot of ¡°stuff¡± and we have retirement.
We all know that a working ¡°A¡± is far better than a non-working ¡°B¡± and I have
not evaluated the items yet but would like an opinion or two on which would be
a ¡°preferred¡± for an experienced hobbyist.
Kind regards,
John
