Title: 274B with Torii Post by orangecrush on 05/25/12 at 19:38:28 Can the 274B be used with the Torii? Note(*): 274B is direct heating tube. The indirect heating 5AR4 may turn on slower, however, people who buy 274B is for its superior sonic performance. To fully utilize its benefits, it may requires first stage capacitor (capacitor input) to be less than 10MFD, or would shorten the 274B life span (very much like smoking is bad for your health). It would not be a problem with common choke input. Please consult to your amplifier maker or refer to a tube manual.

Title: Re: 274B with Torii Post by orangecrush on 05/26/12 at 03:34:05 Yes, I read that initially, but then it seems they burn out fast and now the Zen Select manual says do not use them without modifications. I don't think the Zen's have chokes, do they?
