I'd agree with this. I used to have a 465M and it was a pretty good scope. You can get them dirt cheap on Ebay. For the original poster, if you're comfortable designing, building, and debugging audio

Oh no... it just so happens my wife and I are traveling to Vancouver next week, but I'm sure she would not be interested in taking a day from our vacation to drive to Kelowna to pick up old

Hello: I need to verify the wiring to the fan on the Tek 453 which I just acquired as first scope. Works fine, but fan bearings were dry. Got it going but cannot verify with certainty the solder

I tried that today and it works quite well once you know what to do. Connect vertical output to line level input of a regular stereo receiver or amplifier, plug in the headphones. Digital storage OFF.

Aaaah.... empirical design. This always works.

Maybe if it was a "instead" question it would be an error, but luckily it is only "what first", standard PIs are cheap. I would expect the MF will come with some useful plugins (or it may not if it is

Greetings etc I have a late model 7704A & an earlier manual. BAMA is no help. Z axis board is suffix 01, my manual is for suffix 00. Suffix 01 board shows an additional trim pot immediately below

Hi Walter The 11K vertical plug ins are not simple. Most will give you 1% or much better accuracy. The plug in data and cal info is read by the mainframe on power up so you need intelligent plug in's

i have 2 t932a tek scopes that are excess to me they came from the university of california both are repaired now, the tubes are in perfect condition and i have a pdf of the service manual. where are

Hello Michael, Also measure the unregulated voltages at the filter caps. (Values on the schematics are only crude indications). Low values might indicate bridge faults or open filter caps or a very

I happen to agree with you, with the proviso that a 7A22 is darned useful for audio. My reading was the guy was looking for a first scope for audio. I think it would be an error to get a 7A22 instead

I do repair the audio stuff. My recommendations are reasonable and explained. I don't know the high falutin stuff like yall others, but this other stuff is my fortay. For going out buying DVD players

I happen to agree with you, with the proviso that a 7A22 is darned useful for audio. But lighten up a little is all I'm saying! Craig

I agree. For most work you do not need a fully calibrated scope. ST

Yes. There's the video trigger plugin (11T5H) and its 75-ohm vertical sidekick the 11A34V, at least. To be honest, though, even as a developer of video gear for my day job, they're a bit of a luxury -

I have repaired many a TEK scope, most of the 7603's were the result of human destruction not circuit failure. And of those not needing repair, I have found most of them to be within tolerance and NOT

Stan, I checked the voltages: +100V = 124V +225V = 203V +350V = 306V +500V = 464V -150V = -144V A lot voltage is below the limits. The main supply is switched to 234V, the current standard voltage is
