CPAP power attempt

I was hoping it would work, but given that there are at least two specifications for the 7.4 mm connector, it would not fit my CPAP. It is a great idea though.

Works for non-standard audio effects

Most guitar pedals and effects boxes are standard 9V center negative DC, but my Alesis Phlngr actually needs 9V AC. I had to find the right plug size which ended up being 2.5 mm inner diameter instead of 2.1mm like this adapter. This site also sells the converter from 2.1x5.5 mm to 2.5x5.5 mm that allows me to interface with this unit. Works as intended.

Replacement for BOSS SE-50 Supply

I bought this adapter for my Boss SE-50 since I did not want to spend $40+ on a giant brick known as the BRB-120. I had one of the original Roland power supplies back in the day and hated how much space it took up just for a half-1U rackmount. However the plug on the AC/AC adapter I bought here is 2.1mm x 5.5mm so I also got a converter on this website to adapt it to the 3.0mm x 6.3mm plug in the back of the SE-50. I have confirmed this to be operational, and a less expensive shoehorn for the BRB-120.

Great Power Isolation Unit

I received my 300VA Isolation Transformer and it was in perfect condition. I have shipped and received many equipment but none were as protected as this transformer unit. Packaging is A++. The transformer is package in a nice solid case with a power cord and one output socket. (I wished it had two). I am now using it to isolate my test equipment when in use to an isolated radio product. I am very happy with this isolation transformer unit.

High quality product.

Arrived packaged in three boxes in perfect condition. Works as advertised a full floating transformer with no reference to earth ground.

Does the Job

Bought this for a Bellari VP130 phono preamp since the stock power supply has a bad reputation for noise. Sounds clean when running, had the negative center, and the 15VDC 1A needed.

Hard-to-Find Item for 6.5V Digital Camera

After much searching elsewhere, I was happy to find
this item on your website.
My older digital camera requires 6.5V DC input when
using an AC adapter, and most new multi-voltage adapters
no longer include a 6.5V setting. This one does.
The adapter is well made and includes multiple tip sizes,
as well as a special tool for selecting the output voltage.
The output voltage selector switch is very well designed,
and has nice positive stops at each voltage position.
I also have a newer 5V DC input camera, so it's great to
have an adapter that is so easily switchable.
Shipping was very prompt, and the adapter arrived in
perfect shape.
