On my lunch break today, I thought I would run in to the local thrift store for a little walk around and was extremely surprised to find a Tektronix 545A w/ Type L fast rise calibrated preamplifier plugin. Naturally I had to have it thinking I would do a full restoration so I picked it up, but as I was loading it into the car, I noticed the calibration sticker was from the JPL dated Dec 16, 1974.
Now I am in a bit of a pickle and could use some advice. This is a piece I plan on keeping and passing down to my children (if they show interest in electronics) but my original thoughts of doing a full restoration are starting to feel like a possible disservice to the piece. Granted there must have been hundreds of units purchased by the JPL over the years but still, in some way this is a piece of american history and I don't want to ruin that.
Am I just over thinking this and should go ahead and start tearing into it, cleaning every piece and putting it back into like-new condition? Or should I try to preserve the piece as-is only cleaning it so far as to remove the dust and debris and making just the minimum repairs to get it operational again?
Since this is my very first piece of Tek, I don't know much about the history behind this model nor how to even begin to restore it so if anyone has some good advice, I would be quite grateful if you would share them.
It would be awesome if someone knows how to read the serial numbers and could tell me when my unit would have been manufactured. The serial number is 037375. It would be even more awesome if you might have actually used this piece and would share any knowledge you have about where within the JPL it was located or any projects it might have been used on.
Better pictures will come once I can get some help carrying it into the house.
