5MHz Quartz Crystal - Vacuum Envelope #341

The crystal was manufactured in Russia in August 1974. Individual crystal number is 341, handwritten on the glass bulb. The rhombic sign on the glass means the part has passed military QC. Despite it's age it looks OK cosmetically. The good news about crystals is that they get more stable as they age. So the older crystal you get the more stable it is. The crystals are packaged inside a vacuum glass bulb to secure them from dust and moisture. Lots of gold inside the bulb, cool electrode architecture. The crystal is removed from a metrology equipment where it served as a timebase reference and is guaranteed to be electrically OK.

Actual crystal is on the images above.I will combine multiple items for shipping. Please request the total after you are through offerding, I'll then issue you the invoice for payment. You will be asked to pay actual shipping. Tracking is optional and runs $3 per package. There will be individual tracking numbers issued for multiple packages if I have to split large order into 2000 gram segments. It is sometimes cheaper shipping parts as several packages because of silly Lithuanian Post pricing policy.

Please allow reasonable time for your order to get to you. We are humans and sometimes make mistakes. I am open to solving any problems should they arise before you post a rough response on or escalate a claim.
