I would think this would be one quick and easy solution for those wanting a pre-amp.

I bought a few several years ago for my phono's. Don't have a need for them yet, but heck, I bought them at the Dollar Store.

Let's see. How much did I pay for them yet? Hmmmmmmmm..............

Sorry, I used to go into the Dollar Store and for fun I'd go up to the girls at the counter and ask them how much some item was. Cheap humor.
