No it doesn't. And the only ones I have are in my amps.

It has a 10V heater winding on the tranny, though, as you have probably seen.

But I do have some excellent UX4 Teflon CMC sockets if I can find the buggers. It'd be good if you can slip one in instead of the current one.

The unit like most testers certainly won't be capable of testing a 211. Virtually nothing is. Most are sold untested on eBay for that reason.

Do some Googling and you will probably find some custom built add ons for Hickocks and the like.
