Except a 7000 series with a 7A22 differential amp plugin at 10µV/div ;D

Yeah,the 7000 series are nice old beasts--you can get such a range of plugins.
I'm looking for a 7L12 or similar Spectrum Analyser plugin.
Rotten thing is,I saw several on eBay Aust before I got the 7613,but nary a one,since! ;D

:D I've been thinking about it for about a minute, but I dropped the idea. They are just too huge, and I'm a bit afraid of buying something this old that I cannot really use to its full capabilities.
Currently I'm hesitating between a 2201 (seller refurbished, 30 days warranty, but seems expensive for $150), and a tested 2225 in really good shape (if I can score it)... I've been considering a Hameg given how I have a history with them, but those vernier pots (and all the mechanical wizardry with the front panel) seem really easy to break and hard to fix.

I bought a 2336YA (nearly identical to the 2337) on epay a while back. $50 including shipping. The pics showed it displaying a flat line, turns out the coax going to the input bncs had fallen off. And it was missing a button (trigger view), a chop stick and some duck tape fixed that :).
After I got it (and fixed those two simple problems) I realized there was no freely available service manual. I spent $10 to get an electronic copy of one. So far I have liked it pretty well, though I haven't used it a ton. It is pretty far out of cal, but one day I will actually attempt to get it close-ish to calibrated now that I have the service manual.
The good and bad is that the scope is small and portable. Good being portable. Bad being that things are a bit more packed in when trying to service it.

Lol it's one of these military ones, right? :D Looks pretty cool, but I think I'll stay with the civilian models.
