Tektronix 465/475 Series Repair Tips

A video produced by Tektronix showing some repair shortcuts for the 460-series and 475 oscilloscopes. Surely you have a specially-ground-down 12-point half-inch socket in your toolbox!

Oh my goodness, various parts of my body clenched and puckered when the Neanderthal pot crushing technique was demonstrated. Oh The Humanity!

[@prenticetyndall]

Just grab some pliers and yank anything off the board that needs replacing. Thanks. Got it now. As a 475 owner, I now have PTSD.

[@boblake2340]

I was wedded to 465 scopes for a couple of decades. Best scope ever. Legendary.

I found one neglected in a cupboard at a job I started in 2016. It became a friend :)

[@tootall849]

Just recently did so myself. I feel like it may be the start of a thing for sure.

[@fullwaverecked]

Great tips! Thanks! Here's another safety tip: avoid looking for a small tweaker in my area. You might get shanked, and lose your wallet...

[@MLX1401]

Gotta love that funky hand-drawn insert :D

[@ksbs2036]

Heh, I have a couple of specially ground-down tools in my toolbox from hand-to-hand combat with other bizarrely designed devices. I guess I'll be making another

Next, tie a cable to the transistors emitter and base leads, and then hook it to your trucks trailer hitch. Once completed, hit the gas pedal.

This video is like a "howto destroy your Tek circuit board in 2 easy steps".

Seriously I would have great reservations about using pliers to tear a defective pot right off the board. Cardboard won’t prevent the traces from coming off with the pot!

[@jenniferwhitewolf3784]

That is very uncharacteristic method from Tek... Never seen anything so crude and brute suggested by Tek before.

[@ZXRulezzz]

​@@jastervoid Besides that, they've only soldered a single leg of a new pot on camera. Someone doesn't love the smell of melted plastic in the morning. :^)

[@VintageTEKMuseum]

in their defense, often the reason to replace a pot is because one or more legs are already broken due to a frontal impact on the knob.

[@pamperchusqueek8193]

I love my tektronix

[@georgegonzalez2476]

It would be nice to also mention that the power supply diodes and filter caps are a bit undersized and they tend to fail pretty often. Also isn't one of the capacitors charged with making a thru-hole connection and must be soldered on both sides? Also its ground lugs are tasked with carrying ground currents between the ground lugs. Kinda iffy, fellas.

Defective part? Use some dynamite to remove the defective part and replace it.

[@RingingResonance]

huh, i have one of those!

[@repairitdontreplaceit]

wow brutal . poor scope

[@ReyciclismoMTB]

I have one of each, I have to clean the attenuators to see if it fixes a glitch .

[@zorafm]

How about 485 :(
