The S-5000 runs the 7189s VERY hard. Don't, for 1 second, give thought to trying any EL84/6BQ5 variant! They will quickly fail.
NOS 7189s are scarce and quite expensive. Fortunately, the current production Russian 6П14П-EB (6p14p-ev), AKA EL84M, is a genuine 7189 equivalent available at reasonable cost. The Russian tube is tougher than the proverbial brick outhouse and its sonics are quite respectable. "Roll" the small signal tubes to obtain maximal results.
