Universal UB1640W 16.5 VAC 40VA Plug-In Wall Transformer
This transformer is recommended by PE as good choice to power the new stock Yuan-Jing Lehmann Clone Headset amplifier. But where does the minus 15 volts come from ? Is + and - already split on the board ?
Where is groung on this UB 1640w i want it to replace my old one on my alarm.I am 84 and not a elec.THANKS
What is the actual voltage output of this power supply? I know what it's advertised as, but I was thinking of replacing the PS that comes with the Lepai mini power amps with one of these. Would you recommend these for that purpose?
The output of this power supply is AC and is not recommended for any of the small amplifiers that we offer.

Will this work as a replacement transformer on a craftsman drill 15.6V battery charger? I don't have the original transformer...I tried a 1 Amp transformer and that burned out...
Unfortunately this will not work as a battery charger. You will need a dedicated charger for that specific battery which we do not have.

Can this work to power a door bell
If the doorbell chime requires 16.5VAC at less than 40 VA this will work perfectly fine.
