These vintage power supplies sell for a relatively high price, but I'm not really sure exactly why.
Is someone here familiar with gold pins from this era? There are 2 rows of 14 pins. Additional photos are included in the ebay listing.

Apparently it powers certain vintage microphones that people like.
Btw, your eBay listing is very nicely done!
I know Altec Lansing was a innovative company in the motion picture business. giving us the first sound systems in theaters. If I was to guess late 50's or early 60's by the pictures, can't read any of the date codes. Looking at the control knobs late 50's.
The EIA codes will be six digits before 1960 and seven digits after. The first three numbers are the manufacturer so Mallory capacitors will have a seven digit number 235 (Mallory) 235-6216 would be Mallory made in 16th week 1962. Those Altec Lansing parts will have 391-921 or it may just be 391 921. 391 is code for Altec Lansing the 9 could be 1949 or 1959 (your case 1959) made in 21st week. The knobs should have EIA codes on the back side. Those type of knobs are know as "Chicken Head" common in 50's and early 60's, more than likely made by Daka-Ware. Those knobs can sell for $3.00 to $9.00 by themselves. But I think you will have a buyer, try to precise date the item. I'm just giving you made up dates for reference, as I can't ID any of yours. 235 is Mallory's code and 391 is code for Altec Lansing.
Altec also made some amplifiers also, that unit looks to be hand wrapped.(the components)
Mechanic what's your opinion on dating by just the pictures as they are. I for one value your opinion.

Wouldn't the cap's be cardboard/paper wax type for early 50's? Maybe this device has been recapped? Just asking as I think you have seen more of this type of equipment than I.
The two on the right are paper/wax, the one on the left they may have had to go with that style to handle that voltage (600v.) The soldering looks to be original. The resistors look to be era correct with the carbon type. My specialty is actually CB radio, Miked's is Ham radio
I was sure one was paper, so you did much better than me. Resistors for sure are of 50's era, just caps I was questioning. Thanks for taking a second look for me. Still learning.
Do those paper/wax ones have any more value then newer caps? I got several on a piece of the elevator equipment I got. Was out breaking the sucker down, an saw those. Been meaning to ask, but it slips my mind! On a side note...I got a buddy who stops by just about daily after he's done with work for the day, an he took a look at it the other day an was pointing out all kinds of caps, fuses, etc that could go for more then scrap value.
I'll have to try an get some pictures an toss the info up here.

As long as you don't power them up! Power cords, capacitors are the most likely to fail components in old electronics. A professional overhaul the large electrolytic capacitors and small paper capacitors are almost always replaced. Especially if they have been setting around unpowered. It is called "recapping". Sometimes to reproduce the appearance of authentic era type gear, they will use the old paper caps, like a shell over new caps. More like a facade in an old western movie!
general rule of thumb i have gone by anything to do with high tech and vintage sound stuff fetches a pretty penny
Offhand I don't know of any vintage cap. collectors, lol and what Burt said is correct. Old orig. capped tv's, stereo's, and amps will a lot of time hum and when you go in and recap them it will take the hum away.Quote:

Also the gold pins from the 50's and 60's had alot more gold on them and some might even be solid gold.
I'm by no means an expert but solid gold (high karat) would be soft so I imagine it's just heavier plated.Quote:

Interesting info. Thanks for all the feedback. Got super busy here shortly after I posted this, but was satisfied with the sale.
