Default Re: Amazing D cell discovery!

Actually, if you are building your own op-amp RIAA preamp it makes perfect sense to run it from a couple of PP3s. They will last for years if you remember to switch off when not in use, and it saves the cost, effort and space of building a high quality power supply.
