The ECC88 = 6DJ8. The PCC88 = 7DJ8. The ECC189 = 6ES8, which is a variable mu (gain) type. The PCC189 = 7ES8 and it is NOT suitable for audio service.
AI preamps are notorious tube eaters, as your experience indicates. The "best" tube for service in your unit is NOS Russian 6n23p-ev. The Russian NOS is TOUGH and has decent sonics.
