Excellent product

Used it to power an antique Mr. Christmas Music box. It was a rare 9 Volt AC (not DC).

DC Universal Power Adapter Multi Voltage Output: 1.5V DC-12V DC @ 300 mA; 6-plugs
Seems Decent

Lots of settings and attachments. Should be useful. Bought to replace a plug for a radio. The power supply is some new switching stuff that totally blocks AM. Since no batteries makes no sense! Supposedly a Biden mandate (no surprise).

Variable Transformer 10 Amp (1000 Watts); 0~130VAC Output ISOLATION & LCD Volt Meter
Power Shack Isolation Variable Transformer

Could not be more pleased with the product and service provided. Took a while to find a product that combined a variable transformer with a true MAINS, ground isolation. Unlike most cheaper competitors offerings, the digital readout and dial for this transformer is fairly accurate when checked with a DMM. Great product for a hobbyist tech.
