Re: 6SF5 preamp tubes?!?

Scott	Re: 6SF5 preamp tubes?!? IMO, they sound pretty similar to a 6SL7, but even cleaner. Both the 6SL7 and the 6SF5 sound cleaner than any 12AX7 to my ears, with warmer midrange and better bass. This may be good or bad depending on what kind of amp you are making. I have reworked several PA amps similar to your find and I have always stuck with the octal preamp tubes, but then I use octals for my new designs also.
