® Owner’s Reference BHK Signature AmplifiersCheck to make sure power is going into the BHK and it is connected to a live source. Make sure the
rear panel master power switch is in the on position and the lights near the tubes are lit. Push the
front panel logo light and it should blink, then remain lit after 30 seconds. If it is lit, look to the rear of
the unit and see if the tubes are lit and glowing. If there still is no sound, check the preamplifier and its
connections to the BHK. Check the speaker cable connections to the speakers
PS Audio BHK300 didn’t work this morning.
Last night everything worked fine, this morning my left mono block was silent and only the blue on/off light was on. I checked everything and found a fuse was blown. I checked all six fuses and found the one to the right of the IEC inlet had blown and I replaced the fuse and all the lights went on and the tubes started to glow, but still no sound. I’m sure it’s not the source, the preamp, cables. It’s definitely something wrong with the amp. When in standby, the amp is normally warm to the touch and this is cold. I sent an email to PS Audio and am waiting for a reply. I also put this question on their forum.
Any thoughts?
Jeez, I hope I don’t have to send this 83# brick back to Colorado!
