So I finished building my TSE ii today and am having multiple issues with the checkout procedure. Any help at all would be greatly appreciated! So now for the issues:

-upon inital powerup, it ran for a few seconds and then there was a flash and smoke. I immediately turned the power off and found a burned mark between d2 and d3 on the bottom side of the board (see pic). I looked and did not see any solder bridge between the two nor was there any visual damage to either diode. This event also blew the fuse. I cleaned up the burned area and did not notice any other damage. I tested both diodes, both show .5v and only pass voltage one direction.

– I then replaced the fuse and tried powering up again. I am getting the following measurements with no tubes installed and have no clue where to start on the troubleshooting:

B+ 0v
B- -174v
rect heater volt 0v
300b heater volt 4.98v
5482 heater volt 8.3v

I have uploaded a few pictures of the build. Thanks again.
