OT: Tek scopes

Post #33,958 by a6l6e6x 3/31/02 10:44:51 PM Reply	OT: Tek scopes Ashton, you are terrible. You had to remind me of a day of joy when a Tek 545-B with dual trace and delayed sweep arrived for my use. What a quality work horse that was! Yes, I know it's a different scope, but the model numbers are a hair away in memory.

All those ceramic terminal strips, anodised aluminium - and as close to perfection as a manufactured product might get. We just stood around looking at it, with the covers off. (What a great living room display for the Upscale folk - even today - leaving off the covers! Especially late at night = foot warmer too) As doubtless you are aware, quite a few are still around and in (or restored to) original condition. Pity that 500ish watts is just a bit much and 30ish MHz a bit little :( But with sampling plug-ins, BW is still respectable; not a few 1L4 (?) spectrum analyzers are still being used too. I have a 564B storage scope with a Nelson-Ross audio spectrum analyzer plug-in. Gotta find an audio type to get this one. Clean as new - and the -B mainframe was all solid state (though the Ross unit ain't.) Anyway.. Tek ain't Tek anymore - just as HP has become a commodity reseller of $30 ink cartridges at 500% profit. Still, I've culled pristine examples of the clever Sony-Tek small scopes, like the small 35 MHz 335; another model of same size at 5 MHz / w DVM, etc. These peddled for >$3k towards the end of their run == now just hundreds, and some like new. Someday soon, people won't believe an actual "Corporation" was ever motivated to build such quality. {sigh} Quality - look for that in your local museum. Ashton hoping sometime to steal a 2467-B "Bright-eye" scope, just for the hell of its impossible complexity / simple operation.

Or, the small roll of silver solder inside the case for an unlikely repair? Alex "Never express yourself more clearly than you think." -- Neils Bohr (1885-1962)
Post #34,114 by Ashton 4/2/02 12:39:05 AM Reply	Yup.. Loved the skier.. down a delay-line IIRC !! The little rolls of, technically "3% silver-bearing", not really silver-solder - so as not to cause the 'fritted silver' on the strips to come loose with repeated tin-lead soldering. Perfectionist stuff, and on its own white ceramic-like bobbin! But what the New-Tek is like: I burned up the First e- thing ever (well, almost) on a #$#@% 2430 digital scope: seems that it May Not be operated out of the case w/o "an additional air supply". Now there were labels of usual dummy kind.. CAUTION Glass CRT under high vacuum* and the like.. but only (later when it came) in the manual ~ p.45 was a little note about this peculiarity. And NO LABEL inside the case. D'Oh. Really pissed me off because I was able to cure an error message about a particular part by forcing a re-cal; scope would have been OK. But then I recalled.. in space, nobody can hear you scream.. Grumble, piss, moan
