FS: Amperex 4CX250F Ceramic Tube: NOS Amperex 4CX250F Ceramic output tube. Tube was mistakenly purchased to replace a 4CX250B. As we found out, the circuit for the 4CX250B is a 6 Volt filament as is the 4CX250B. We then found out that the 4CX250F uses a 26.6 Volt filament source…… so this tube is up for sale as maybe it was developed for military use with that filament voltage? $30 shipped CONUS.

811A tubes (5) USA (old stock) excellent: Photos available on request since site limits to only one Photo. Anymore these can be nearly $100 ea. Tested good++, USA (near) NOS vacuum tubes. No damage or repairs, solid caps, sockets and prongs. I only briefly rotated them into my TenTec Centaur, when cleaning/dusting the equipment and bench, so as to check them and give the amps original Svetlana 811s a wipe off and "vacation." I learned that under typical conditions 811A tubes don't get gassy in storage like some others (572B) but I know it also doesn't hurt to let them glow once and a while to prevent problems. Only ever used for brief periods about 3x and only stored as spares. One or two may include a test value sheet or be written on the box. I was very picky patient when shopping for USA old stock tubes, when I had my TenTec tube amp, as they are known to be as durable as the original Svetlanas in that amp. Yes without abuse these USA tubes can last decades. These are fine tubes. call: 850-296-4194 Asking $170 all 5; Listing #1703153 - Submitted on 09/23/24 by Callsign KG5OVI - IP: 173-17-160-171.client.mchsi.com; Click to Contact -- Click Here to View Picture -- Send this Ad to a Friend
