I am not aware of any replacements for these..maybe someone can correct me. The 6h30 is supposed to be a "faster"sounding more accurate valve. My listening impression of the 16Mkll confirm this as a good sounding and immediate sounding tube, but not as warm and transparent as my LS15 with NOS tungsrams.
