Default Transistor types in Bi-Pak AL60 modules?

I am trying to find the transistor numbers on the AL60 module.

Could anyone tell me the numbers of the small transistors and the one in the middle of the heat sink.

A list would be useful going from bottom left (component side) across the board.

Also the transistor on the middle of the heat sink.
I used TIP 41A for the power transistors in the past..however I have lost all the info I had.

Its a nostalgia trip...I made two stereo amps many years ago using theses modules and I found a photo of the track side of the board.
So I am thinking of making a couple just for fun..

Here are the pics.

Thanks for any help.

Regards, Tubeglow.
