I'm having a hard time finding Toshiba 2SA970 GR or BL transistors for the input board of my Adcom GFA-555. The issue is mostly finding them at that grade (i.e. MCM has them, but ungraded). I'm sure there must be a good substitute, but I lack the skills to confidently identify one. Does anyone have any suggestions?
Many thanks.
