Tek 2xx 211, 212 Scope questions, possible Z input and # of grids in CRT, etc.
My 214 and 222 do not. No. The 214 is an analog storage ’scope, so quite different. The 222 is a different size.

sony/tek 468 is it rare?
Looks to me like the same as the TekWiki photo, differing only in a broken Cursor / Sweeps knob and yours has a darker CRT filter.

I've got the BNC version of this: http://www.leobodnar.com/shop/index.php?main_page=index&cPath=124 I'd bet a lot of us have at least one of them.

Need help fixing tek 214
I have a 214. I installed NiMH packs to replace the failed original NiCd packs. It works well. See https://w140.com/tekwiki/wiki/214 for schematics. I’m afraid I don’t recognise the component from you

Tektronix 465 Fan Motor not working! Help!
Fan speed is temperature controlled, but on startup it should spin -- though slowly enough to be quiet.

crazy question: 191 const. ampl. generator
I'm the proud owner of one Type 191 in as-new condition. I mainly use it for its intended purpose, measuring the bandwidth limits of (mainly) 'scopes & plugins up to 100mhz. It seems a shame to modify

Thanks, and good points — I’ll keep my eye out for better probes in original condition.

P6137 probe parts wanted
I just acquired a P6137 probe fairly cheaply, and I can see why - it's been assembled from other probe parts and the indicator switch on the cable assembly (174-1081-04) doesn't work: what I assume is

There is a 2466BHD on the auction site
But eBay Japan seems fine, or at least it worked from the UK when I looked at the 2466BHD listing last night.
