[Hallicrafters] Hallicrafters HT-33A

[Glen Zook]

I just obtained a Hallicrafters HT-33A linear with a bad final (PL-172).  I believe that there have been some articles on changing out the tube with a more readily available tube.  However, I have been looking on the Internet and just cannot find any.  In this case google is not my friend!

Does anyone have a suggestion as to where I might locate this information?
