My ebay watch list is filled with obscure tiny scopes.  At one point I was even convinced to make an instagram for my NLS ms-15 scope :P.   Although tiny spectrum analyzer add on for tiny scopes are also great, I love the tek 1401.  For great obscure oscilloscopes I love the yamaha pt3 tuner, it was a scope designed for tuning instruments, a very specialized piece of adorable kit.

Final check out of the 535A. Attempted to do some frequency response checks. Things didn't go so well as I'll explain.

The set up. Tek Type 191 Signal Generator. It can go all the way up to 100MHz.



I attempted to trigger on a 11MHz sine wave. No go. It wasn't until I lowered the frequency to about 9.5MHz that I could get at least some trigger. If I lowered it more down to about 9.1MHz I could get a stable trigger. And that's the disadvantage of these old tube triggers. The manual states it good to 5MHz and I guess they ain't kidding. But I was able to stretch it the 9.5MHz.

Here it is right at the limit at about 9.5MHz. Very unstable. Sweep speed set to 0.2us and 5X mag on. Aptitude set to 1.0V p-p. Any higher than this and it drops like a stone and screen goes blank. 



At about 9.1MHz it's stable.



At this point this project is done.

That is a super-cool little unit.  Instrument tuning is a lot easier and cheaper nowadays!

I'm new here, but I tend to be pretty gregarious, so if I'm out of my lane please call me out.

^yes, the Snarks cost like $8 or something and work incredibly well...  the Yamaha tuner must have cost a fortune in its day.

Way back in the dim dark past a Brass Band I was playing with got one of the early Yamaha Digital ones. I have memories of it topping $400 30+ years ago.

Interesting little fellows those snark tuners.
5yrs ago I was associated with a very serious Pipe Band (City of Adelaide) and was heavily involved in the tuning up process - we used Korg tuners initially - to get things close then used the interference 'beat' to finalise. It was quite difficult as bagpipes are very loud- esp if you are in the middle of 10-15 pipers playing their warm up set.
It is a long process - would take the best part of an hour to get all the pipers each 3 drones and also the chanter tuned up.
If done properly, you don't get the 'orchestral' effect and it ends up sounding like a single 'big' piper.
Unfortunately there is a lot of bad piping out there.
Whoah! Watch where that landed we might need it later.

Most impressed with the new Bosch. 20 20mm holes 40mm deep only into MDF but the hottest part of it all was the Fortsner bit.  :-+

The middle holes will need to wait for some modding and I really should actually print out a 20mm chamfer bit I designed several weeks ago  :palm:

Oh, I see now. The holes are so when you and your drunken arse spill your pint, it just pours through to the floor instead of washing across and landing in your mate's lap...  :-DD

Just right to keep my "Dwagon-Size Teriyaki Beef Slim Jim" from rolling off and getting lost in the peanut shells on the floor. Well done! :-DD
