Malcom,
Check out Andy Bouwman at Vintage Tube Services. He is a dealer on A'gon and is very reputable. Besides that, he is about as knowledgeable about tubes as anyone you could find. If he can't help you then very few can.
I would suggest that you get his phone # from his web site which is www.vintagetubeservices.com and give him a call. He is very slow to respond to email so using the telephone is your best bet.
Good Luck!
