I have in my basement an unbuilt Heathkit 5 MHz scope! (Flea market find!) Interested? 😊 (I was thinking of using it to build a scope clock, but the thing will be huge)
If you are not used to a digital scope, they do have a learning curve although the number of on-screen measurements and hold functions are awesome. Yet I still often go back to one of my analog scopes, especially when working with low frequency stuff. Whatever you do, try to fix the old scope, and keep it handy. I have as my main scope a 300MHz Tektronix TDS3250 scope, now 13 years old. It died recently. Turns out is has a Dallas (Clock / ram) chip with integrated battery. The battery died, the Dallas chip is unobtanium, and is very efficiently soldered into the board. No parts to be had. I found a chip in China, but since it is old stock, I have no idea how long that one will last. (I got the old chip out with my Hakko desoldering rig, and put in a socket) There is a lot to be said for the old scopes! Bill v.

My Tek 2236 is nearly 30 moons old and no longer stays on for more than a few minutes. I am sure it's fixable, but on the other hand maybe time for a new digital! What do you guys suggest for general use and of course clock fixing? -- You received this message because you are subscribed to the Google Groups "neonixie-l" group.
