Looking for a single 300b

While taking a monoblock to my technicians, I hit a big pothole, the amp tipped over, and one of my JJ Full Music 300bs shattered :-( Anyone got a single out there? I can ajdust bias on each tube individually, so as long as it's a good tube I should be OK. PM me thru the Audiogon system if you have one or know where I can get one. TIA.
