The bias test jumper in the DX2517 and other sideband radios is commonly called the "mirror board" because of its shiny surfaces. But it's just a jumper wire. Pull it out of the clips and you complete either the driver or final transistor circuits through your current meter.
But what to do if the copper foil traces under the board will no longer support those spring clips?
Here's one way.
Or you could just solder wires on the foil side of the board. This way makes it easier next time bias current needs to get checked.
