Default Need a transistor for a '70s Zinger Color Organ

Hello. The Zinger is a six light alternating and flashing unit. It could run either on with varied speeds or connected to a speaker wire or radio output to pulse with the music.
I am trying to fix this bedraggled old thing ... I know, glutton for punishment. Anyhow, the transistor (which is quite toasted) is a Toshiba FIR3D41. I can find no info online
about this part or what the replacement might be. Based on what it is supposed to do, are there any suggestions for a replacement? It is 120v and the model number is 528. Thanks
for any info !


I have a feeling that you will probably need to trace out the circuit
and draw a schematic, in order for anyone to figure out the actual
requirements.

I suspect that the FIR3D41 code might be either a house number, or a
manufacturing date code. I have little doubt that there are
compatible parts available today (probably an arm's-length list of
them) but without a schematic it's going to be really difficult to
select one.
