My advise is ask a ham operator. Half of us have several scopes collecting dust and will not list them on eBay cause we ain’t hurting to sell them.

AGES ago I got a ISO-Tech ISR622 20MHz for about £20. Still in use, still works for me. Old school, low res, simple CRT...brilliant!

Every time you do a $50 eBay oscilloscope or cheap online the eBay an online guys all raise their price the same day when everybody goes clicking and looking for cheap scopes, the price skyrockets

It's amazing how much of DIY electronics is searching for tools and components. And having to learn the hard way that what you ordered, isn't always as good as what you expected.

I recently found a Tektronix 475A with the DM44, manuals, two P6063 probes in nice condition for $25 at a hamfest. Bought it, gave the switches a good cleaning and replaced the rear feet. It appears that it had been serviced a few years back because it was not suffering from any of the common issues these units have. Went through the routine in the service manual and could not find anything really wrong with it except the calibrator is about 200mV over spec.

Bought mine from the lessons from your last video.
Went for 100 bucks but the seller provided a warranty, the scope had 60MHz and 1 Probe was included.

And for the low end digital scope, I made one from a Raspberry Pi Pico overclocked to 2MSa/s

I scored almost exactly that HP 54645 at a college selling old equipment. I paid $80. Universities are sometimes good sources of test gear, computer equipment, or even some office equipment. If they have a property disposition center anyway....

When I started my bench scopes were expensive and hard to find. Craigslist is full, I've been buying them and giving them away to students. By the way, I picked up 4 working Teknetics 2 channel scopes for well under $100 USD each. They work great!

I was recently rewatching those videos. Scopes spark joy

Its really hard to justify 100 smackers for a 70s scope unless that's specifically what you're after

I picked up 2 broken Tek 465's for $30. This was just for parts for my working one. Got a front cover and full service manual in pouch (just those I think was worth the money). Narrator: He never got around to try fix the broken scopes.

I bought 8 scopes in an auction back in 2019, Mostly LG Goldstar OS-9020g, but there were a few others in there as well. Tried to sell them for $50-60 a piece on marketplace and got my A$$ chewed out, finally took them down and just gave them away to folks who wanted them. But i got message after message from hateful people on marketplace saying old scopes aren't even worth giving away. I was horrified! Never listed anything for sale on that despicable place ever again!

Rather than scanning ebay for old scopes one could look for dave's dumpster for scopes :P With dave getting so many new scopes for teardown review I am sure some of them would be going to the out as well........I am buying tickets to camp out side Daves office....:)

For $50 I got a beautiful analog scope with the digital multimeter.  Iwatsu 100MHz scope in new condition. Just keep eyes open for local listings. Scope is in nearly new condition and screen is perfect.

Those HP scopes like the 54645D, have awesome UI and responsiveness. They are just so fun to use.

most of the scopes I've gotten have been free from schools or oldie engineers who have a broken unit in their garage. the rest of them were broken cheap and local (but also ancient).

Im one of ur fan sir
I lived in phillipines
Ill always wached ur infoemative video

Ahhh.... As an Aussie, you clickbaited me in right there.  Oh well, it worked lol.

Never could figure out how to setup Ebay Watchlist to that it worked.

Still pretty happy with my Tek 2212. Weird hybrid thing, 60MHz analog, 20MHz digital bandwidth. $80 and a can of contact cleaner for the knobs!
