Maxon OD808 problem

Can someone help me?What is the proper voltage for Q2 collector?I guess it should be around 4.5v right? I am getting a very low reading(.730v) and the gain pot does nothing.Is this because of the poor voltage of the collector?What is the bias resistor for the collector of Q2?Thanks in advance

Update:
I also measured the opamp.it reads:
1>1.78
2>1.76
3>.763
4>0
5>1.69
6>1.69
7>1.68
8>8.92
I am sure these are poor readings.I also installed a socket for the Q2,and even unsocketed the pin for the collector reads .730.Any thoughts?

You must have a misplaced link or maybe a cold joint or unwanted bridge somewhere.  The voltage on both transistor collectors should be 9V.  Have you put the double link in as shown at pin 8?

Ii was that damn double link!I made it but i got something wrong.I made it second time and it worked!It is really late here in Greece so i cant test it now,i have to wait untill moring.Thanks Mark!

Ok now its working but the sound is not that good.The Q2 base reads 5.6 and the opamp 6.5.They supposed to be 4.5?

Those readings where made with a 4558P,with 4558D it gives 7.5.Is those values high?
