xrk971 Pocket Class A Headamp GB

[xrk971]

It's snowing today as I walk to work. The handwarmer feature of this amp comes in handy. It really does keep your hands warm in a snowstorm.

Of course all the while enjoying your good Class A sound.

But perhaps your regular Home Depot matte black paint can work fine. Anything is almost better than bare shiny metal. I know Kapton works very well and also acts as electrical insulator to prevent surfaces from causing shorts. The tape is much cleaner and leaves no residue to flake off.

If you do use regular ol' spray paint be sure to scuff the metal first (steel wool works well) and apply a layer of primer before painting. This will help prevent flaking.

Piece of tape is so much simpler.

PCB's Shipped!!!

Good news folks. I just shipped all the PCB's today. So within days (US) and maybe a week or 10 days overseas you should be getting your board(s). Please post a note when it arrives so I can track progress.

Happy building!

I have had some requests by some folks who want the amp but can't do SMT soldering. I can offer the option of a pre-built and tested amp board but you have to install it in the mint tin yourself. If you are interested in the pre-built option (hand built with matched FETs) send me a PM.

Matched FETs

I think that my boards are in the mail, but I would be interested in hand matched FETs.

I would too, if it can be worked out.

Another member actually requested the same thing. Price is $17 for one set for one amp and $5 more for two sets for two amps or $22. This includes shipping in the US. For outside US, add another $5 or $22 for one set or $27 for two sets.

It takes some time and a large stock of parts to make this happen, and it looks like this is of interest to a lot of people so probably I need to order a large order of BF862's and ZVN4306GTA's to have enough stock to perform a good match.

Matched BF862's and ZVN4306GTA's for my two boards.

For those interested in using this amp but don't want to do any soldering or ordering of parts, I'm offering fully populated and tested PCBs with matched FETs for $200. All you need to do is install it in a mint tin or other case of your choice. Order here.

Please remove me from the list. I'm going to build with my unmatched components and then reconsider whether or not I need matched components. Thank you for offering the matched components.

Please remove me from the list as well, i would do the matching myself.
