Mystery of the Dead Dr. Z Maz 18 Continued

I didn't anything on 1000 DC.. when I moved down the scale it started at .8 and and very, very slowly moved to zero.. same on both sides of the resistor..

OK
same conditions as above...set meter for DC 1000
Output tubes removed
power on, standby in operate position.
can you check for DC voltage at test point 3?
I'll draw it on the photo.
There is a bare metal spot on the exposed lead of the resistor that's not covered. Try touching the red probe there and see if there's DC voltage.
Push the point of the red probe right down inside the black tubing, and touch on the metal lead.

Sorry brother.. I don't get any DC voltage.. I have the power tubes out and the power and standby on.. should the pre-amp tubes be in or does it matter..? They've been out..

You are doing fine.
The tubes can be out that's good.
You can put the clamp back on the capacitor.
Follow the wire that is connected to "3" in the photo, can you take a picture of where that wire goes to?
Follow the brown wire that is connected to the filter cap in the photo, can you take a photo of where that brown wire goes to?
Follow the orange wire that is connected to the filter cap in the photo, and take a picture of where it goes to?

# 3 position (red wire) other end of chassis
Brown wire just to the right
Orange wire up above left

OK
where the wire goes:
test both sides of the resistor for DC voltage, same as before.
We are looking for a resistor that has voltage on one side, and no voltage on the other side.
You are going to find it.
 
I'm sorry.. I don't see any dc voltage to ground on any of those points.. or any other point for that matter... probably doing something wrong..

OK
put the black probe on the chassis
Use the red probe to test pins 3 and 4 of the output tube socket.
You were reading voltage there last time you checked.
Now double check and make sure the meter is working.
 
Ok... I cleaned the crap out of my probes.. went back to the original resistor ohms question..
I'm now reading the correct ohms for both resistors that are at the cap coming in on the blue wire..
I also measured the resistor on the other cap that comes from the blue wire connection.. it is ok as well..
This amp came to me from shipping.. not sure what actually happened in transit.. the 1.5 amp fuse was blown when I first fired it up.. tried it again after getting some fuses.. it blew again.. I changed the rectifier and fired it up.. this time the main fuse blew when turned on but the 1.5 amp held... I replaced the power tubes.. fired it up and everything held but no sound.. here we are..
It could be something really simple from shipping I guess..
