Default Ross pc-4110 amp circuit or help

How zit all ! Please help. Got this system in and people (bush technicians) already had a go at it.Want to try and repair , but not sure if the right transistors is in and if wired correctly. The output transistor is not solder on
the pcb. Instead it is wired. So now I dont know if it has the right parts in it and if it is wired correctly. Any one have advise or know where I can get the circuit.Will post pics if someone is willing to check it out.
Regards
Vick

Hi Vick, yeah go ahead with the pictures, I'll give it a try. I love to debug!

The output transistor is wired? That is strange... Unless it's a TO-3 case mounted on a socket that had solder terminals.

Thanks Enzo for the reply.I know about Musicparts.com and found it
when I was searching for the schematic.Unfortunately it wont be worth to buy.
I will take time and figure it out or better yet just replace the amp.
Regards
Vick

That's really an absolutely horribly constructed amplifier - however, it should be pretty simple to draw out the circuit of the power amplifier, which will make it pretty easy to repair.
