New TEK Scopes

[andyjevans]

My humble opinion. Clean the controls and use the scope as it is.>

that's the advice I've had so far. I don't know if I could do this - never seen inside a scope. It might make sense to have a service/clean rather than a recalibration. the money would be better spent by the look of it.

Hi andyjevans,
Well, at least you'll know that the scope is fully functional then.

If you ever get a meter or 'scope calibrated (anything really), make sure to get the data and they optimize the unit. The only handheld meter worthwhile is a Fluke. They will hold their calibration for a long time.

A while back, I got a Tek 454 off the fleabay for 50quid, but the CRT was well past its prime--

A lot of searching round on the 'Web, turned an unused boxed CRT tube up in NYC< so I got that, fitted it and all is well--The new CRT cost me 50 quid but was worth it as the 'scope was in otherwise excellent condition, and where else could you get a 'scope built like a brick-outhouse and 150Mhz that cheap, with a new bright sharp trace!--

It even uses tubes (8393 Nuvistors) in its front end and part of the horizontal ccts. and not having those difficult to get chips and other weird devices is easy to repair should it need it.........

By todays standards, its an absolute dinasaur, but great for audio and beyond, and I love it!
