The 221 etc. series scopes still run fine nowadays. You need a calm
hand and a lot of experience to keep them healthy. But in the end, for
using in field service at a customer site, I like these small scopes.
The BW is low (0.5 up to 1 MHz, depending on model).

221 was 5 Mhz,
213=1 Mhz,
211-212-214=500 Khz

But most times
enough for the things I have to do in field: get a quick impression of
where the fault is, these scopes are real helpful.

The battery and the plastic molded case gives my most time problems
when I get these units for repair.

Personally, the 213 with the integrated DMM is what I enjoy most. It's
a good combination, and still useful in 99% of my service work.
If you take a little bit of care, and handle these analog scopes well,
they last real long.

The plastic pins in both case halves are important,they retain the circuit
board's position,keeps the interconnect pins from spreading the receptacles
open and the tiny leaf spring from falling out and shorting things.They
caused a few meltdowns,with those NiCds.

213 and 221 were the best of the 200 series.
