Good morning all.

I've started my build and the secondary voltages don't measure correctly. My line voltage is 119V +/- so I used the wiring instructions on pg 31.

I get the right voltages at 7 & 9, but 0L at 11 and 12 on both amps. Not sure what I'm doing wrong here. Any advise or troubleshooting tips? I've built at least 8 other BH pieces with no issues. Replies appreciated.

TIA. Aural Robert.

Your meter likely isn't autoranging, so you'll need to turn up the AC voltage setting so the voltage coming out of the transformer isn't over limit.
