So I ordered the kit for the Bijou from glassjar audio and the build went smoothly. The amp is working, but after probing around with the multimeter I'm curious about something...
With the Amplifier boards disconnected from the power supply, the b+ voltage reads exactly 250.0V, however, when I connect the boards and have the amp running (no input connected, just in standby) I read 138.4V from the b+ wire.
Is this standard? or is there a problem with the amp boards drawing too much amperage for the voltage regulator to keep up?
I'm using a 270DAX and an EZ81 for the rectifier, 2x JJ E88CC and 2x 6N6P for the amp boards.
