The 845 tubes can NOT work on a 805 R-800i amplifier, the 805 tubes can NOT work on a 845 R-800i amplifier.
They are completely different amplifiers.
What is difference between 845 and 805 tubes?
Usually, the 845 tubes have a smooth sound, it is good at human voice, very nice sound, but the power is not too high, so, 845 fits the speakers are high efficiency.
805 tubes have a high power, so, it work well with most of speakers(but please don't use 805 at a pair of very high efficiency speakers), and 805 is good at large dynamic musics like Symphony, jazz.
