[Boatanchors] For Parts/Repair: Vintage Lambda Model 50 Power Supply

Hello All,

I have the good fortune to have too many Lambda Model 50 power supplies and the shelves are straining under the weight.

There are 4 available, with one having an outer case with no latch on the rear door (some missing paint on top).  Of the remaining 3, one has the original top and rear perforated covers.  The remaining 2 do not have a top or rear cover and I think one of them has a broken corner on the voltage meter (not sure if there is any functional issue or not) and there is a missing knob on the main variac.  Operating from memory here...if there is sufficient interest I will post pictures somewhere.

The one enclosed with an outer case has no tubes, the other 3 are missing their 6L6 and rectifier tubes but I believe all other tubes are present (but no guarantee they are good).

Use them for parts, restore them and put their 500 regulated DC volts at 500 mA to work, or use them for incredibly heavy bookends.  At over 70 pounds each they are sure to keep your entire set of Encyclopedia Britannica upright and presentable.

For a reference set of images, look here (not my auction, mine have more dust):  http://www.ebay.com/itm/Vintage-Lambda-Model-50-tube-type-regulated-power-supply-MASSIVE-/112145658498?hash=item1a1c66f282:g:v6MAAOSwIgNXr77O

Now for the details:  

1.  I will not ship them.  You and/or your trusted agents (friends with good strong backs) will need to pick them up.  I will not pull any parts to ship separately.  I live in Inver Grove Heights, MN, and the units are in my garage for easy access.

2.  Price is non-negotiable at precisely $0.   Sorry, I can't go any lower as I would be losing money at anything less.

3.  First come, first served.  I'm going to list these on the antiqueradio.com site as well to reach a broader audience.

5.  Offer ends October 2, 2016, at 6:00 pm, Minnesota time (Central Something Time).  After that they will be recycled.

Hope to hear from you soon.  I really do.

Best Regards,
