Audio Note Quest 300 wiring 120v

[kiran1103]

Hi. Bought an audio note quest 300b that’s wired in series for 240v. How do I wire it for 120v. Pic attached and if u need the underside as well I can open and take pics. Thanks.

I think is

0 with 0
and 120 with 120
But if you a a tester you can measure the Rdc from0 70 120 in upper row
and same in bottom row,
must be equal

In the photo the jumeor means that the two primary are in series

Better ask the manufacturer as it seems confusing. Logic says 0 to 0 and 120 to 120 but it is Audio Note and if it is a DIY kit certainly be careful. Probably you need to use one of the fuse holders for 120V too. The wire instead of a fuse/fuse holder is also a bit worrying. Please note that the fuse value is dependent on mains voltage. Make sure it has a fuse in the mains circuit for your safety.

Tip: add nylon washers to that 4 bolts.

from0 70 120 in upper row

I mean 0 to 120 volt

Type error

Thank you all. I will write to AudioNote and get it confirmed. Logic said for parallel 0 to 0 and then 120 to 120. I will check with multimeter on continuity to confirm the connections to L and N.

Thank you. I got it. This is how I will do it and should be a breeze. Thanks once again,

What about the fuse? Ha simultaneous post!

Yes I changed the fuse to 3.15amp. One is working and the other one no audio output. Only the rectifier heats up but 300b and 6sn7 slightly warm. Something in power supply went bad. Troubleshooting it
