Being an HP retiree, I never got to play much with Tek scopes outside of my 7 years with Texas Instruments and engineering school. I do know they were built _almost_ as good as the equivalent HP scope.

I've got an HP 1700 series, 100MHz scope myself. Make sure any tantalum caps inside are replaced. They were used extensively in the power supply decoupling on each board and when they die they go out shorted.

Cheers,

David

That is a nice scope!

Congrats

another HP retiree. HP scopes were somewhat known for triggering problems on occasion. Tek made better scopes IMO. But I have a HP scope bought at HP employee discount. A "no-brainer". Oh, and it's "nix' just like its spelled.

Damn! I wish they would have spelled my avatar 'Teknix' so there would be no debate! :banana::nono:

That's not a vintage scope...

This is a vintage scope.

Eh, that's still too fancy. THIS is a vintage scope:

50s/60s/70s is all vintage to me. 80s NOT. all junk.

That Tek 545 looks like the one on my bench. The only difference is that mine has the 1A1 dual-trace plug-in instead of the CA. Those old Tektronix scopes were built like tanks and would run just about forever.

I'll offer one of these as a "Vintage" scope. I actually own one of these in it's original case, and it works perfectly.

I run it up on a variac every once in a while. No hum. :thmbsp:

The Tek 454 still has a few Nuvistors in it's front end. Good scope.

I've posted these before...

The Heathkit, sadly is toast (I think the PT is shorted); I kept it because it was given to me by a friend from church (who built it). The EICO works but needs attention (capacitors I am sure).

mhardy, I dig that Heathkit. It's like mine, but it actually has useful things like scales.

mhardy6647

Yours doesn't have scales!? :-(]

Found mine at the dump; I have its FM cousin, too (AJ-63)... bought that one at the Westford (MA) antique radio fleamarket a few years back.

Nope. It's the same as the much cleaner OL-1 in the picture I posted. It will give you a waveform, but no measurements against it. I still need to find some probes, it seems to work fine.

Sorry, I thought I was responding to another thread entirely :-P

That is a beautiful photo of a beautiful scope.

That first pic looks like something you'd see in a ship in an old war movie. Captain, I'm picking up something on sonar...

Nah...You boys are all wet...EVERYBODY knows what an oldish scope SHOULD remind you of- "There is Nothing Wrong with your Television Set..." I threw the covers over my head MANY a night back then....(grin)

Nice 'scope! Really like those Teks. That model always looked real good to me, tho never had one.

Am a big fan of Hitachi scopes, too. Have a V212 and a V1050F.

Here's my vintage scope (awaiting tubes), Heathkit IO-10.

I kind of have the same problem with oscopes as with audio. :o

My "everyday" scope is actually a Kenwood :-)

I have a lot of NOS tubes kicking around, what do you need?

The Kenwood. Sorry it is grubby (it suffered smoke inhalation in its former owner's shop in a fire). I have actually cleaned it up somewhat (it's not exactly pristine yet, though).

This is a cute little guy. Savvy thread-readers will readily identify the OEM of this little "RCA" scope...

Just one more downstairs (I think)... maybe I'll snap a photo of that hulk, too... later.

Those way outclass anything at my house...

FWIW, I did find a photo of the little Tek 310A 3" vacuum tube scope with a trace (sorry it's a flatline at the moment the photo was snapped).
