Here are a couple sent via the amphon email chain:

Build your own replacement from Dave at 'Manualman' :  https://tubesound.com/solid-state-replacement-for-83-tube/

The one on ebay looks nice, probably built from the Tubesound plan.

Thanks to all who chimed in with ideas.  The fellow in need at the Southern Appalachian Radio Museum  only found Type 83's for $80 to $100 and was amazed at the prices.  I thought it was a high vacuum tube, but, as noted in a reply, it is a mercury vapor as spec'd.
