These are great scopes. Very durable. It you open it up, you will see all gold plated circuit traces (if I remember correctly).

Which ones, the BK that the OP mentioned, or the HP I just bought?

 

You're lucky you didn't have to restore one that looked like this. (unless you find that kinda stuff fun).

Thanks for the link, that was a very nice writeup!

I'm a member over there at the EEVblog forum, so I suppose I know who to go to if this thing doesn't work right

Cheers,

I'm assuming the HP. They made top quality stuff and still do now that they're Agilent.

Sorry, the HP is the great one.

 

If you want to buy a scope for second hand, you should ask them to guarantee that the scope is good, or you can fix it by yourself.

I had bought a IWATSU SS-7821 200MHz, and I didn't use it very often, but after one year later, the scope was damaged, when I tried to fix it with my friend, we checked out all of the parts which could be damaged, the result was that the CRT was damaged and there is no way to fix it.

And then I bought another old one IWATSU SS-7810 100MHz, it cost about US$100.

We can buy a old 20Mhz scope around US$10~40 in Taiwan, it depends on the conditions of scope, that is guarantee the scope is good.

You can also to download a sound card scope to test it, but the input signal have to be less then 1Vpp, of course you can using the resistors as a voltage divider to reduce the input voltages, and it has a signal generator, you can use it to test the audio amplifiers.

Sound card scope.

Looks like a nightmare restoration. Excellent.

I'm pretty sure I tried that one.
For audio I use the sMexoscope VST http://bram.smartelectronix.com/plugins.php?id=4
and ASIO drivers to get low latency.
