HA-1A Headphone Practice Amplifier – How to purchase


As of January 2015, the HA-1A is no longer being manufactured. I’m hard at work designing the HA-2, which will be similar in function but somewhat smaller in size and will use an internal rechargeable battery.

Please follow Cafe Walter Audio on Facebook to learn about the progress of the project. My hope – safe harbor, no promises, your mileage may vary, et cetera – is to have it ready by mid-2016.

Thanks!
