New old stock IEC Mullard (International Servicemaster) 6JN8 vacuum tube.  Triode and pentode in same envelope.  Made in Japan.

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 invoice.
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 available.
