ASR 33 on ebay UK

Looks pretty complete. That 50hz model would be very rare here in the states. The hand-markings near the manufacturer's plaque make me question if it might have been adapted to some other voltage.

A good find for someone in the UK, although perhaps a little expensive. Then again, they're not making any more.
 
I'm really tempted by another ASR-33 on eBay here in the states, but the price of $1k + shipping is giving me heartburn. And to think that I used to have two of them that I gave away for free. DOH!

Another issue would be supplying the power needs. It's not a simple matter of a transformer for the correct voltage... 60hz vs 50hz would require a 50hz Smart-UPS.

But seriously, and returning to the original topic form my threadjack:

Does the Model 33 set its baud rate based on the line frequency? It's been a long time since I've been inside one. I have more recent familiarity with Kleinschmidt TTYs (Baudot type, for communications rather than computer use), which have a mechanical speed governor that the operator adjusts by using a special tuning fork. If the line frequency determines the baud rate then I would hazard a guess that Teletype used the same old motor on that 50 Hz model but changed the gearing on its output.

I gave away one years ago too. I kick myself every time I think about it.
 
What I can't figure out is why they are so rare.
They must have built tens of thousands of the things!
 
And I can't figure out why they're so expensive now! Must be because of idiots like me paying stupid money for them? :lookroun:

I had an ASR33 here in the UK 25+ years ago: it had a huge transformer in the bottom of the pedestal to step down from 240 to 115 volts. There were no other particularly obvious additions or changes to get it working with UK line voltage and frequency.
