I hope that by this point you have downloaded a service manual.
You are doing nicely, most likely Q5 has died, it is a common occurrence - the transistor is overworked for it's size. The replacement I have specified in other threads is a larger cased transistor that will shed the extra heat more effectively - at a price of maybe having to enlarge the holes the transistor leads fit into slightly to get them to fit.
The MOST IMPORTANT thing is to get the correct lead into the correct hole - there are six possible combinations of which only one is correct. The guys should find and link to my explanations of the transistor symbol printed on the board.
edit: this will help a little, read at least the first page of posts, there are useful diagrams:

this is a load of reading, especially with the links, but is does cover a lot:

Q5 is (the larger packaged):
AWR-101: Q5 2SC1318 ecb
512-KSC2690AYS to-126 ecb 120/a160 1.2a 20w 155mhz 35-320hfe $0.40
or it could be (the SMALLER packaged):
512-KSC2383YBU to-92L ecb 160v 1a .9w 50mhz 160-320hfe $0.17
both numbers are from mouser.com, and the extra data is to assist if you try to obtain the transistor or an equivalent locally. Preferably NOT NTE (long story).
You will notice they both are ECB layout. the guys should explain... that is with the lettering facing you, leads pointing down, going left to right. The original 2sc1318 is also ecb, but we can't trust that blindly. We use the symbol on the board to designate which lead goes into which hole.
Now, there is a small chance that Q5 won't get it going (don't worry about pin 11's 28v, that 28v depends upon 8.9,10's +36.5 volts being present. That 28v only runs the phono amplifier section). Then either R6 or C18 is at fault. The big parts list (costing under $15 iiac) does list C18, but not R6. But I can come back with a part number for R6, if needed.
(You could rebuild the board from that list, ensuring a higher level of reliability.)
Upon the chance that Q5 replacement does not restore the +36.5v (+/- 10 percent) then voltage reading from the three Q5 leads will be needed to locate less probable reasons for the failure.
