These 1033 transformers are worth from 25 to 35 dollars at auctions around the US. They are all over. it would cost really more than it is worth. some one might buy it if cheap enough.  Put it put on OGR selling point and see what happens.   Postage will cost more than it is worth.  If you know of a train store maybe they will trade you for something you want.  last resort take to you town's recycling place and dump it into the metal bin.

The missing bit is a circuit breaker (1034-17), which has been replaced by an 1144-12:

  I'd check to see if the transformer coil is actually working before trying to replace it...

You can also replace it with a 5A breaker from an automotive parts store, it's probably a better circuit breaker than the old original.

You can use this one if you can find it:

See attached pdf for detailed info on the 1033 and more transformers.

That gives you all the information you need if you decide to jump in and repair.  Jumper across the circuit breaker to check to see if you have good voltage.

Thanks all for the terrific and helpful information.  However, I'll be listening to Harry Callahan on this one; " A man has got to know his limitations.".  I've recycled it rather than electrocute myself.

I've recycled it...

Oh no! These have decent value to those that find this an easy fix!

@ADCX Rob, from the schematics @Susan Deats supplied, the adjusting screw was still there but it appeared to have corroded.  Half of the circuit breaker was missing, there was a hole where it was.  It just looked to be in bad shape.  I had no recollection of owning or buying it or even using it.  I'm guessing my dad got it from some friend and just added it to the box, he was a bit of a hoarder.  When I resurrected the collection in the mid 80s after 20 years, I did buy a new Lionel transformer at the time, can't remember the number.  So, with that one, a working 1033, and a newly refurbished ZW, I have all I need.

There aren't many train meets in Houston that I'm aware of, so I have no chance to sell or trade it.

My grandfather did a similar thing, he packed away one working 1033 and the one he used for parts. The insulation on the old cord was shot so I replaced that with a new one (no ground). I took my sd70's off the rails a few weeks ago and I've been running my old 2026. I think it may be time for a new rectifier, I can hear the fan start to whirl in the tender but it doesn't have enough juice to whistle.

Thank you, Susan, for posting that information.

@turkey_hollow_rr, I loved my dad very much, but he was a hoarder (not over the top though).  It would have never occurred to him to buy one of those for parts since messing around with electrical stuff like that wasn't something he'd do.

My grandfather never bought anything new. He was king of the garage sales!  He told me that sometimes he would see a box of train stuff and offer a few dollars for the whole box. He grew up in the depression and was a picker waaaaaaayyyyyyyy before those guys showed up on tv. He was able to assemble a complete train with cattle car and milk car and their accessories. I think he would have been fascinated by Ebay. :-)

Just for a point of reference, that was the way it was issued from the factory, nothing missing.

@Chuck Sartor, Well, since it didn't work at all, I assumed the gaping hole in it was the problem.  What that means is that fixing it would have probably been more difficult.
