accidentally create a short circuit between two component legs with the red probe, cover the probe with
insulating tape, leaving only the very tip exposed.
If you don't have a clip-on ground probe, a makeshift (but less safe!) alternative is to hang the negative (black)
multimeter probe in one of the cage nuts of the GA15 chassis (Figure 3). Use the front left one if you're right-
handed (Figure 3) and vice-versa. Then use one hand to check for remaining high voltages with the red probe.
Figure 3. If your multimeter does not have a clip-on ground probe, a (less advisable) alternative is to hang the negative terminal in one of
the cage nuts (after switching off and disconnecting the amp), so you can keep one hand free for safety and take measurements with the
other hand.
HT fuse F3
Figure 4. The HT fuse F3 (DON'T TOUCH IT!) is a good place to check for remaining high voltages after switching off and disconnecting the
amp. Hang the black (negative) multimeter probe in one of the cage nuts (as described in the text), so that you only need to use one hand.
With that hand, hold the red multimeter probe carefully against the HT fuse and check the voltage.
