Headphone Amp

[Caedarn]

I would really like a headphone amp that would work with pedals. Can’t use the amp as often as I’d like!

I have hand wired up a circuit pretty much like the apps note for the MAX9722 that works for driving headphones. I am also using The UniCab and a Frog preamp (this uses a 12ax7 tube) in front of it. This works pretty good for me. The MAX9722 is TSSOP so I got a breakout board from Adafruit. There is another package for MAX9722 and it has a different pin-out. This schematic is for the TSSOP.

Maybe something like this could be an option for the UniCab?

Here is the schematic (I don't guarantee there are no errors). I used MLCC for the 1uF. This circuit doesn't do any tone shaping. It is just a headphone driver.

Thanks - have you run pedals into it?

Not directly. The frog preamp and UniCab make a big difference. Right now my signal chain is MDMA, Van Pelt, Module 8, frog preamp, UniCab, tuner, DI box to house. I get a return from the house that goes into a beringher personal mixer. The out from the mixer goes to my headphone amp. I didn't play with it much at home just with pedals.

I think the big thing sound wise is the unicab. But it won't drive headphones well.

I'll also warn you that the TSSOP footprint is pretty small.

Thanks. I’ll check it out.

Thanks for the reply - did you mean to post a link? I'm not seeing it.

the link shows up when you place your mouse cursor over the "drumming and headphone" text. otherwise you do not see the link.

Thanks. I first viewed it on my phone, so didn't catch that.
