Does anyone have one or two 12SB7 tubes? These are the same as 6SB7 except for the filament voltage. If so, please reply direct to me.

These were made by RCA for the military (I think it was an Air Force contract). They are still listed in stock by two military parts suppliers (though at extremely inflated prices...you know like the $900 hammer).

Thank you in advance to all who reply.
