What was your question?

Since this seemed to have nothing to do with eBay, I moved it. Surely you could have found a better category to post it in.

Like resabed01 asked, what is your question?

I'm sorry
I understand
I just need some help to recognize this modules
Is that audio equipment or some vintage parts of telephone central to sell them on Ebay or if somebody have experience and knows is there some values in it
Thanks

I'm not sure exactly what they are but seems to be some type of Russian Telecom equipment judging from the writing on the front of the module.. common in, common out, line busy, etc. I'm not seeing Tesla anywhere? Hope this helps in some way.

Last photo, lower left, TESLA is etched on the board. Tesla is a Czech company that does indeed make telecom equipment - the name is an acronym for “Telecommunication” and “Low Voltage” in Czech language. No real association with Nikola Tesla.
They also made electron tubes, prized by some audiophiles.

The modules look to be transistor amps and switches. PM type or quantity unknown.

Cheers,

The points on the contacts in the picture with the removed solenoid will be a combination of silver/Palladium/Platinum. The fingers will also be extremely good. I processed some of this equipment only just before Christmas.

You also need to look at any gold contacts because no mater how small, they are very heavily plated.

The power units don't contain much in the way of precious metals but the control/switching units can be high yielding.

Hope that helps.

Edit- a ps for the other commentators- yes this gear is Tesla.

Thank you for the response
I already pull out some of the fingers They are fully gold plated.
Can you share some yield data from your experience with this

I didn't keep individual yield figures as we were refining it for a client and they wanted an overall figure but from the whole batch we recovered an excellent amount. If you look closely there are a lot of those items you have in your hand hiding in various parts of the switching mechanisms. You must remember to keep the circular switch stacks too because the plating on the armatures is incredibly thick. Don't throw anything away that looks like a contact at this point because PGMs were used very widely in this equipment, and it's easy to mistake them for non precious metals especially when the units are dirty inside.

ps. If you want to pm me some pictures of some of the internals I would be happy to point you in the right direction. This kind of equipment is rare for a home refiner to get and handled correctly you can do well from it especially if you have a lot.

Thank you for the advice
I will wait for more info of this units maybe 2-3 days -because my first idea was to sell them like working units (because i receive them in a box properly packed and like i see they are new old stock never used)

Anyway if i cant find any info about them I think to harvest the values and to sell it to someone here in the forum -who will known the history of this scrap

For harvesting the points from the reed relays - & then recovering the Ag & Pd you might want to read this thread :arrow: http://goldrefiningforum.com/phpBB3/viewtopic.php?f=34&t=23091&hilit=contact+points

Sorry but yes contacts from this type gear can be Pt --- in fact sometimes they can be Iridium --- Pt & Ir point are not real common - but they do exist

could you bend the top of a few of those reed relays over & take a pic of the points on the contact end so I can see what the points actually look like ?
