Replacements for the 2N5875 under-playfield power transistors

The factory fitted 2N5875 (10 A, 60 V) or MJ2955 transistors on small brackets under the playfield. Better replacements are 2N5879 (15 A, 60 V), 2N5880 (15 A, 80 V), 2N5883 (25 A, 60 V) or 2N5884 (25 A, 80 V). The current rating matters more than the voltage.
