Why balanced microphone cable at the input? Left and right channel wires are close to each other, which is bad for crosstalk.

There are all kinds of wire to try! :D

Are boards for this going to be available on the diyAudio store?

6L6 24th January 2018 10:20 PM

Yes, we're working on that now.

I am trying to track down the heat sinks that are used for this headphone amp.
Does some one have a part number and suppler?

I think these are the right part - 531102B02500G Aavid Thermalloy | Mouser

1" pin spacing, and choose height to fit in your enclosure of choice

In the process of building this. I have an earlier rev board without the 2k2 resistors between the inputs and the pot. How important are these? I have the pot on a separate board so I can just insert them if that's better. Can other values be used?

Ah sorry, I had not looked properly at the schematic. So i suppose i can just add them if i need to lower the gain a tad.
