Hi there! I just read the thread concerning the 6X5 in the 42-380. I just checked my 42-380 and sure enough the 6X5 is the recitifyer. Further, the tag on the inside indicates it's original to the set. I am aware of this tube from other applications and since I got this set working nicely, I sure as heck don't want to fry it. Is there another rectifer that can be directly used such as the 5Y3, 5U4. Is there a schematic for replacing the 6X5 with silicone rectifyers as Ron suggessted?

Thanks, Mike.
