12V 1000mA AC-AC Linear Power Adapter 2.1 x 5.5mm plug

AC-AC Linear Power Supply

Professional-grade AC-AC Linear Power Supplies designed for applications requiring clean, traditional transformer-based power. Our AC-AC adapters feature a robust internal transformer design, ideal for sensitive electronics, audio equipment, and vintage repairs.

  • Input: 120 VAC @ 60 Hz (Standard US Plug)

  • Safety: UL/cUL or ETL Approved & RoHS Compliant

  • Design: Durable wall-mount or desktop transformer housing.  Also available center tap (raw) transformer.

Important Technical Note: These are non-regulated linear power supplies. On an open circuit (no load), the output voltage will typically measure 1.0V to 1.5V higher than the rated voltage. The voltage will drop to the stated level once the appropriate load is applied.

Awesome experience

Web site was very helpful to make sure I had the right replacement plug and it arrived in a few days.
Had to cut the plug end off to replace a hard wired plug from an old Halloween decoration but it worked and saved a 25 year old holiday decoration.

Variable Isolated Transformer 10A (1000W) 0–130VAC with LCD Voltmeter | SC-10T-2
What an INCREDIBLE deal, what service!!! I'm be buying more!

I bought the Variac/isolation transformer combo. FOR STARTERS: NOBODY ELSE MAKES THIS COMBO with a genuine isolation transformer. And that fact that it's $200 out the door is insanity. My only advice with the unit would be to double check the voltage display against a multimeter; I find my display to be about 5V lower than the actual output and adjusted accordingly.

This item was packaged more securely than a nuclear warhead. Seriously, the packing job is a masterclass in transportation and logistical safeguards.

In short--I rarely leave reviews. I felt I HAD to for this product. If you're not sure because it's a newer item/company, don't worry. They are LEGIT and they are INCREDIBLE.
One more side note--customer service response is insanely fast also. I emailed a question on a SUNDAY EVENING and got an answer.

GREAT, domestically-owned small business I will support again.

Replacement for Morpheus Droptune Pedal

Needed a replacement for a few guitar pedals. This is a perfect replacement for many pedals. Just verify center polarity and amp requirements.
