hello,
I'm building a clone of the Roland Dimension D (SDD-320) and so far the only problem I've found is how to replace the output transistors (Q106,107,108,109).
They used 2SC495 and its complementary 2SA505.
I'd like to use in-production transistors, I don't want to source those old parts.
Is there an equivalent that would reduce to min. the modifications on the schematic?
