12v linear power supply

Those used sboosters go quick. 

Honestly,  idk about what amps I needed. I thought I was just suppose to look at voltage. 

 Would you be able to build one yourself? AMB has a couple of versions that are very high quality. The completed kit would likely run $100+ and be a reliable and able unit.

I don’t have the time to learn... not yet anyway. Saw these. They seem OK enough. But has me wondering about Amps now because they have 3 different versions. 2, 4 and 6a.

Ah. I understud Amps now.  All I need is the 2a :)

I always over spec my lps, less stressed, better reliability. So, you need 2amp, I'd get lps that could supply at least 4amp. I see too many posts of poor experience with lps, always because people purchasing lps that can only maximally supply needed amps, heat and stress lead to failure. Don't cheap out on lps!
