This reminds me of? a "folk cure" often tried years ago on TVs. Instead of using the 2nd anode voltage, a hand held Tesla coil was used. If there was gas in the tube, the glow revealed it. Often, one

We have added more Tek knobs and TM500/5000 bits, plus there's an excellent audio power meter, tons of connectors from mil circulars to BNCs, HP 8620C sweeper scales, all kinds of board assemblies,

Many years ago (far too many to disclose) I used to go out to repair rental TVs. These were valve sets and the practice to brighten up an ageing CRT was to take the eht cap off (using insulated tools)

Hi all, I have an AWG510 here running Program Version: 1.6B and OS Version: 1.1 I want to update it to the latest version 4.0 downloaded from the Tektronix website but I am having problems. I have

The fuse holders in the 7704A are a bit like some that are used in older HP gear where the fuses are held plastic cylinders that that are attached to an outer housing. Removing the housing exposes the

I had a 19" arcade game color CRT that was very dim... since they are not rare, I decided to experiment with rejuvenating the cathodes. Applying a high positive voltage to the grids (through a

I haven't tried this, but you might consider drilling a hole in one end, say 1/16 inch, and then taking a wood screw or drywall screw and threading it in.? If nothing else, it will turn the fuse and

Getting the fuses out is probably a bit more difficult that inserting them. The inner edges of the end caps are much sharper than the very ends. There's not much room to break the fuse as the plastic

I recently repaired a similar pot+switch (311-1192-00, 10 kΩ) on a 465B. It had suffered a front impact that had deformed support plate inside the switch which then prevented the switch "arm" from

I need to replace the 311-192-00 pot/switch A/B Trigger controls in a 468 due to failed slope switches. Apart from some clear frontal impact issues I've also found failed switches in other scopes. Has

I did the Z compensation; it improved the blanking a bit but not completely; I suppose it improved it 2 extra clicks of the timebase knob. I guess it's not particularly a big deal. If I really wanted

Picked up an auction win 7704A today and immediately powered it up only to find it was completely dead. The line fuse was blown, which should have been a 4 A fast blow, but was 3 A slo blow. Do the

Typically a tube especially a CRT is a hermetically sealed envelope. The pins that protrude the tube are a special alloy that has a very close thermal expansion and contraction rate as the glass its

in a nutshell, your scope is working correctly. Your expectations, and possibly your understanding of the controls is iffy. Please don't take this as an insult. The 453 is a relatively old scope, and

so in a nutshell,is my scope triggering iffy?

Like these: https://www.thingiverse.com/thing:4168123

Looking at the pictures of the front panel controls on TekWiki, and reading the manual, it sounds like the 453 only supports triggering on Ch 2 in the NORM trigger mode selected by the TRIGGER control
