Doepfer A-139-2 Headphone Amplifier
Anonymous 06.08.2015
A very basic headphone module but works perfectly. I bought this module to replace my previous Eurorack output/headphone module and the Doepfer module offers greater volume which I required.

The two audio inputs have individual level controls, allowing you to get a good balance in your headphones.

No frills here, but totally recommended.

Cheapest you'll find it
SolideSnaak 13.05.2020
Useful little module if you plan on listening to your modular system through headphones or small speakers, and you won't find it cheaper anywhere (at least I couldn't).

If I would have to give one criticism is that they didn't use shrouded headers on the power connector so you could theoretically plug in your power backwards, but it's clearly marked so that shouldn't happen.

Warning. This module can kill your eurorack!
Andrew FJ 31.08.2023
One amp IC is constantly running at 122°C. If in contact with ribbon cable it can cause a short circuit, and I've read on the internet that some people had this unfortunate experience with A-139. Also, the build quality is ok but there's hardly aby noise filtering components at the output which is why module so incredibly noisy. I don't recommend it simply due to risk of burning your entire synth.
