Second time buying these LM317/LM337 supplies. The best design I have seen anywhere near this price range. Well designed and good quality components. With protection diodes, Vadj bypassing and much better filter capacitors than many. Great value. One of several great values at this store.
Thank you for the prompt shipping and good products. This is a very nicely designed dual power supply. It has protection diodes on the 317/337. It also has adj terminal bypasses and overall capacitors for low noise. Recommended. Very good price too.
