Item Description: This is a DIY kit which needs to weld each component together by yourself. It can input DC/AC power,but only can output DC.

Features:
1.Excellent connectors. Two inputs and three outputs (a main and two auxiary outputs) make it more convenient to operate when the main output is connected to the Banana jack.
2.Adding a transistor to support load for protection. Even the regulated power supply can be adjusted by LM317T, the load will be burned with the poor contact of potentiometer. Then a transistor can play an important role to support the load for protection at this time.
3.With the dimensions of 30*25*30mm, the heat sink provides LM317T with enough area of dissipation.
4. PCB four corners with studs plus nut fixing, making installation easier, place more stable.
5.Brand new original suite and A level PCB with the thickness of 1.2mm. Pad with solder coating makes the welding much more easier.

02 December 2012 <br/> Prompt and considerate service What an excellent service. I ordered a T-shirt in large and it arrived in a medium. However, the customer service was excellent and I received another one free of charge the next day. The service was extremely efficient, the ordering process simple to use and the T-shirt quality excellent. Despite the hitch, I would definitely use this company again because they dealt so well with the problem and the results were of a very high quality.

Great online storeI've used Barringtons sports on a few occasions mainly to purchase cricket equipment and never had any problems. Delivery always arrives promptly. Products genrally priced competitively and often run special offers. I'm having to return an item at the moment as it's too big and get a replacement size and this process has been very simple as well, including ability to drop off at collect+ centres.

Excellent service I cannot speak highly enough of the prompt service I received from Shoetique. I received my shoes the next day postage free and there was also free returns if I needed to do so, It was better than fighting my way through the High street crowds.
