The attenuator and timebase cam switches should be cleaned with little strips of bond paper soaked in isopropyl. That's a very fussy job, but I wouldn't use anything else on them. The service manual

hi, this may be helpful identifying potentially problematic tants. i would not replace them until you start having problems...but if you were to do that, i would start with the ones flagged as

I strongly suggest you get Caig MCL or whatever it is called now - Moving Contact Lubricant. Faderlube is the new name I think. De-Oxit *MAY* do damage to some carbon deposit controls. Yes, Ideal

I have just bought my first scope from ebay, tek 2213A (Ser. B020545). Wanting to use this for working on 70s/80s solid state audio stereo amplifiers. Have done a bunch of searching on old forums

Hello all, This is my first topic/post. I have a working 465B that I use often in my vintage audio hobby. It works OK, but I had to take it apart to lube the focus potentiometer and lever switch

Hi All, I just wounder if the right group for the PSD2521G power supply. If not please point me to the right group. it DOA and I found that 5V short to GND. The problem is not from the components

I have some basic repairs I am considering for my newly acquired mostly functional 465, serial# >250000. 1. CH2 vertical attenuator cleaning (50mv/100mv/200mv setting shows a nearly flat line until

Would it be possible to use a 3" computer fan mounted on the back of the scope? The OEM motor and fan could be removed all-together and a computer fan mounted directly on the back plate to pull warm

I know it's an amazingly long shot, but I have a lonely CG5011 that's pining for the fjords (sorry for a pulse head). Does anyone have a suitable pulse head that they'd part with? Ideally it would

Ok. I was not aware that there are 7xxx 'scopes that have such a limited bandwidth, but checking the TekWiki site shows that there are 'scopes (7313, for example) that have BWs as low as 25 MHz. The

External for multiple scopes. 7000 series scopes can be calibrated with plugins, and you end up adjusting the plugin's gain (without knowing if it or the scope is right) for a decent answer. Take

Dave Daniel.. the fastest 7000 series scope I have is 100Mhz.

Hmmmm... I'm going to check the attenuator modules in my flaky 7A26, 7A22, and 7S12.  If all else fails, I can bring them into work, where we have higher power microscopes. Say, anybody have 7000

Thank you for the 2213A reply! As far as I know, all of the aluminum electrolytic capacitor are suspect, as well as the the X2 and Y2 film capacitors that see the input AC. Replacing the small 10uF to

It looks as if it were meant for a 500 series scope. The PG506 (amplitude) does the standard 1-2-5 sequence that Tektronix likes, and will work in a TM500 series frame. The TM501 is effectively a

What is the fastest 7xxx ‘scope that you have? Sent from a small flat thingy

So, circling back here, am I better off with an external calibration device to service multiple scopes? For example, right now, I have four 7000 series mainframes (one of which is the military grade
