I was looking for the charger for my big flashlight today. It uses SLA batteries so I knew I was looking for a big one. This made me think of the wall warts that I have saved over the years. I opened the box they are in and out spilled a **** load of wall warts and 3 Laptop power supplies.
There are all kinds of DC supplies here. I feel like throwing them away is wasteful, but... what to do with them? I could use one as a DC supply for my FP 2 heaters. It doesn't hum but I guess the DC would lower the noise floor.
What about those laptop power supplies? A couple put out 15V at an amp. Are they some kind of switching supply? Is that bad for audio use? The only other thing I can come up with is putting a DC supply on the 2A3s in each of my Paramour 1s.
How do you guys feel about these cheapies?
