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.

gain-wire Thanks for reply will put up the pics A.S.A.P

if pc4110 is the board number, what is the make and model of the unit it is in?

Here is the Picture's

Here is another one.

The last one.Thanks for the interest so far gain-wire and Enzo. The model number is the same as pcb. The output is Tip 35 c x 4. The drivers is Tip 31 c x4.

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.

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.
