8874 Ceramic Triodes: Excellent condition, low hours. $399 each or 3 for $900 shipped CONUS.; Listing #1765819 - Submitted on 04/23/26 by Callsign K1FIE - IP: c-50-189-24-238.unallocated.comcastbusiness.net; Click to Contact -- Click Here to View Picture -- Send this Ad to a Friend
NATO Milspec 8877 Ceramic Triode: This is a milspec Eimac 8877 ceramic triode, NATO# V06-0001-000 5960-00-313-6715 sh:2921
It fits perfectly into any 8877 socket since the OD is identical to consumer grade Eimac 8877. But the inner heatsink is 2X the surface area of Eimac consumer, and the heatsink metal itself is 50% thicker than Eimac consumer (see NATO-Consumer head to head heatsink photo)
It has been tested to legal limit power which it achieves easily. But it’s clear from looking at its physical characteristics that NATO wanted and got an 8877 that could be pushed harder, for longer, and in more extreme conditions.
The tube has been tested (anode characteristics consistent with being clipped into a rig for testing), but otherwise it appears to be in unused or very lightly used condition. Comes in original packing materials.

RCA 8122 tubes lot: Here for sale is a lot of used tubes that are 8122s they are RCA tubes. These were spares to my national NCL 2000 and I picked up here and there along the Hamfest path as a vendor, I would see these and buy them. I knew they were getting hard to find and wanted spares for my national amp .I sold my amp five years ago and forgot that I had these still in my closet. The plate caps are pinched, these are pulls , they was pulled out by a pair of pliers so these are pulls .I tested these tubes in my amp and they were all good with good outputs . The price for all five tubes is 250 shipped I can take credit card payment debit card payments cash out Zelle Venmo please call or text me if interested thanks Ken KT4KI Birmingham Alabama, 205–518–3173; Listing #1765686 - Submitted on 04/21/26 by Callsign KT4KI - IP: 107-217-34-192.lightspeed.brhmal.sbcglobal.net; Click to Contact -- Click Here to View Picture -- Send this Ad to a Friend
