Those are both correct. In addition, there is a ground cord attached to the rear upper hex post, and a detachable knob on the front volume control.
The cost of using this information is to share with me any good sources of good NOS tubes, especially Siemens, etc. (Just your sources, not the actual tubes.) I'm still using the stock 6822's...
So the instructions would go like this (being very careful everywhere along the way):
- power off the X-CAN;
- disconnect all cables, both front and back;
- remove the volume control knob from the front (it slides straight on and off);
- remove both hex nuts on the back;
- remove the (philips head) screw on the back;
- remove and set down the back plate;
- remove the lower hex nut on the front;
- while holding the front plate, remove the upper hex nut;
- the LED is still attached, so, while being careful to push the PCB through from the back side at the same rate, pull on the front plate -- once the front plate is clear (maybe an inch or two), you should have enough slack to pull it off and set it down in front of the X-CANv2;
- you should now have access to the front tube socket without fully removing the PCB (it's sitting on little "rails" -- slots -- that are built into the case, like a carpenter's tongue-in-groove -type of situation, with the PCB being the tongue) -- the PCB will sit comfortably unsupported, but I would support it when doing any manipulation, or when more than half-way out, you don't want to arch the board at all and potentially damage the printed circuit connections;
- with a little bit of manipulation, you should be able to access the back tube by almost completely pushing the PCB through -- almost all the way out, from the front (you may need to manipulate the front plate so that there is no tension on the wire);
At this point, you can replace the tubes with whatever you wish.
Reassembly consists of pretty much doing everything in reverse order. A couple of helpful points, though:
- you may want to put the volume control knob back on early to help you steady the front plate;
- be careful about the wire -- it can get close to the tube, but you want it to be as far away from it as possible;
- when reattaching the back plate, do the top hex nut first, making sure that you loop the ground wire through the top hex nut before attaching it to the case;
- last step: enjoy!
PS Headwize is back up, and it seems to have the archives, if there is a good link, someone can feel free to post it, and I'll see how well I did.
If someone wants to make any corrections, let me know, and I will edit my post. Also, please also PM me, as I have been having attention and retention proble
