[Boatanchors] OMG I just blew out three Tubes in my Regen.. Looking for tubes

[whitebear1122 at comcast.net]

Oh my gosh, I can't believe what I just did.  I was experimenting with my SkyMaster homebrew three tube regen receiver and I accidentally blew out all three type 30 tubes by accidentally touching filament voltage with 27 volts oscillator voltage.  Geez.. aw darn...  As soon as the incidental contact was made, I saw a brief glow in the tube and knew what happened.  I went through my tube stash  and have no 30's.
Someone was selling some 30's on the list a few weeks back.  I wonder if any of those are still available.  
Looking to buy at least three type 30's tubes, plus a couple of spares now....  Want working tubes as I now have a 'stash' of duds...Thanks.
