Millett Hybrid MAX

Well, the PCBs from the group buy, MOSFETs (IRFZ24N /IRF9Z34N complimentary pair) and high-quality pots from AMB audio shop, and 7-pin PC mount sockets from TubeDepot have been ordered.

I still have to source some appropriate tubes (probably 12AE6 or 12AE6A, likely on eBay) and place the order for the bulk of the parts from Mouser. But the difficult things have been selected. :D

Soon and I will be on our way to completing some of the Millett Hybrid MAX headphone amps with MOSFET-based output stages.

I’m thinking I’ll follow Matt’s lead and mount mine on some sort of wood platform, surrounded by a cage. I’ll probably also incorporate an iPod dock / charger so I can use it where I use headphones most; on my desk at work.

UPDATE: Five NOS GE 12FM6 tubes purchased via eBay for US$20.50 shipped. These have a slightly lower amplification factor than the 12AE6/12AE6A tubes which most people seem to use for them (13.5 – 10 vs. 16.7 – 14.3), but I don’t think this will be an issue.

Now to order the first go-round of parts from Mouser, Digi-Key, and wherever else is needed to ensure that all required parts are in stock. Oh, and an FT232BM to replace the one I stupidly cooked last night.
