6au6 tube equivalent

Fisher 500B Tube Receiver for sale. The most sought after and best sounding of Fisher's vintage lineup of receivers. 32 watts a channel. Taps for 4, 8 and 16 ohm impedances. Matching quad set of the highly rare and sought after Westi... The US version 6BQ5 and 6BQ5B are not quite as good as the European Pentode versions. The Russian equivalent version is 6P14P and a higher rating type is 6P14P-EV. I believe that 6P15 is a close equivalent too. There is not many near equivalents to EL84, but there is a few. XL84 is a 8V heater version and LL84 is a 10V version. I thought about building a unique amp using a 6au6 preamp, and 2 6BM8 tubes (each have a triode and pentode) for the PI and finals. It would be about an 10w, AB push-pull amp with only 3 tubes if I used a solid state rectifier. I don't know if anyone even makes those tubes new anymore, but there seems to be alot for sale used or NOS. Peace ...

Octal tube with top-cap connection to triode grid. Has three identical diodes—two diodes share a cathode with the triode, one has an autonomous cathode. Used as a combined AM detector/AVC rectifier/FM ratio detector/A.F. amplifier in AM/FM radios. Typically, all sections of this tube are arranged around a single heater. I have a little FM tuner that has 3, 6BA6 tubes in it. I asked if one blew out and I had only a 6AU6 as a replacement, which stage should I use it in?
