New old stock GE 12DE8 vacuum tube.  Diode and pentode in same envelope, designed for use with 12 volts as the only supply.  Made in USA.

Shipping can be combined with my other tubes, sockets, and parts for sale on my ebay store, $0.50 for each additional miniature, $1 for each additional octal.  Add to cart then request total.
New Old Stock (NOS) tubes come in original boxes unless otherwise mentioned.  Sometimes box styles will vary.  Box may have suffered shelf wear, tabs may be torn, may have price stickers or other writing.  Unless otherwise mentioned, I have not tested the NOS tube but will refund or replace tubes that do not meet original specifications.
While stock is available, I will attempt to meet brand or sub-type requests that do not require detailed inspection.  Some types have additional stock or brands available.

Buyer is responsible for any import fees or duties.
