I'm using a big Ken Rad 5U4G Military type from the early 50's, or it could be the mid 40's. Still works, sounds great
but may be hard to find.

Question about 5u4 tubes ?
I have been looking at 5u4 rectifier tubes. Do the older, wider "S" type tube bottles sound better then the uniform straight bottles? Are the old RCA 5u4 tubes the best of this type? If so, are these RCA's better types in both the above configurations? I guess what I'm asking is for an expert to give me some relative background on which type would be best for my preamp which uses only one of this type...but I want the best sounding one I can find. thanks, Jim
