I have that style of transistor, it's TO-92HS or a TO-92 with a flag heatsink good for 1W.
I would put in a TO-220 part, it's closest.
Q32 NPN 2N4425 40V 0.5A 0.9W hFE 180-540
Q33 PNP Sprague TZ525
It's a two-transistor limiter circuit, controlled from the console Rev/Aux switch P1-4 and Q33/Q32 turn on the LDR light bulb M1 to limit volume.
I would use:
TIP41C, TIP42C 100V 6A 2W hFE=100. hFE is lower but the circuit has feedback to accommodate.
TO-126 parts are OK too like
BD140/BD139I could not find specs on the driven light bulb, it seems to get up to 15V off the 33V rail, and is mated with assembly LDR 030379 on the crossover board.
