Raysonic's SP-88 is considered as a one-of a kind integrated tube amplifier in the high-end audio market.Not only it has featured with all the line signal inputs found in most integrated amplifier but it also has a built-in phono amplifier for turnable input. We understand digital audio source is pretty popular in these days and more importantantly we acknowledge that record vinyl has made a strong comeback as well.

The power tube 7591 used in SP-88 is a small beam power tetrode,common in old hi-fi and some guitar amps.7591 was Popular in early 1960s and was originally designed by Western Electric.Currently Sovtek now makes a direct replacement,the 7591EH,It is about 3/16" larger in diameter then the original 7591A,but works fine.If they don't have any then the amp must be converted to 6L6GCs (this is a considerable modification,it will give less output power).Note: JJ is manufacturing the 7591S,which is the same size and diameter of original 7591A.
