Sold (Aus): Millett Mini Max

Up for sale to Australian buyers is one of the finest and sexiest compact DIY headphone amps available, the Millett Hybrid Mini Max headphone amplifier. The amp is one of two that I built as part of a group buy that I organised and represents the absolute best selection of parts you can buy, without just wasting money. I built two in the possibility of having a desk rig at both home and work, but am now moving to Canada for work and need to sell one to help fund the move. The amp has just ~50 hours of burn-in and listening on it...... and it does indeed sound awesome with my ATH-AD900 and ATH-ESW9.

Amp details:
Factory-machined Mini Max case
Vishay resistors throughout, except R1 (heater voltage knockdown)
Panasonic FM at all electrolytic power cap positions
Black Gate NX boutique caps at CA2 and CA7
VitaminQ 0.18µF boutique caps at CA8
Genuine Toshiba 2SC2238/2SA968 output transistors - very rare! Set at 50mA class A bias
22R KOA/Kiwame output resistors *see below
24VAC, 1A power pack (for 240V supply) internally fused with 1A slow blow
Power supply set at 28VDC internally
Alps RK27 50k volume pot with aluminium knob
Neutrik 1/4" heaphone jack
Gold plated RCA inputs
22AWG silver plated copper signal and power wiring
Test points for tube bias
The full BOM is attached to this post in zipped .xls format

With the amp, I am including a set of each 12AE6A, 12FM6 and 12FK6 tubes. The 12AE6A have about 15 hours on them, all burn in, as I found that they had too much gain for my sensitive phones. The 12FM6 have less than one hour on them - one of them is really microphonic so I never bothered, but I am including them at a discounted price. The 12FK6 have about 40 hours of burn in and listening, and are a great set of tubes - my favourite. I will pre-bias whichever tubes the buyer wants to 14V, but I would strongly recommend that any potential buyer has a multimeter to be able to bias these or future tubes for themselves.

Cosmetically, the case isn't perfect, having some machining marks on the top - this is exactly how I received it. The front and back panels are impeccable however.

* The 22R output resistors are the default BOM value, and a good all-round choice for ensuring that the amp is usable with both low and high sensitivity phones. But I am willing to customise the output resistor value based on the buyer's needs at no cost. If you will ONLY ever use the amp with low impedance high sensitivity phones, I will put some 33 or 47R in there. If you will ONLY ever use the amp with high impedance low sensitivity phones, I will put some 10R in there. If you want to keep your options open, keep it at 22R.

Cost:

Amp: SOLD - this is pretty much exactly the price it would cost you to buy and ship all parts (see BOM), without any assembly. It is also cheaper than commercial options that, while still great value, don't have the expensive BlackGate NX capacitors, don't have the rare 2SC2238/2SA968 output transistors, and come with only one set of tubes.

Shipping: SOLD. This covers registered and fully insured postage anywhere in Australia. Buyer will eat PayPal fees for credit card, but there is no extra for PayPal direct deposit. NO E-CHEQUES! If you are in Perth, PM me and we might be able to organise cash payment and pickup or delivery to save shipping.

Thanks mate. After all the work of the group buys, the builds and the photography, its nice to think that I have created something special. I just hope that somebody with some spare cash agrees, and can treat them with the respect they deserve!

(Mind you, my photography was much better on my second amp after I bought my dSLR, and on my second y1 when I was using much more appropriate aperture settings)

All of my previous interest want the DAC alone, and I would prefer to keep this as a package...... so this is officially for sale!

The package is being split up.

The amp is pending sale, so the y1 DAC and cable now for sale separately!

Significant re-jig of the original post, with more info and photos for the y1 Dac.

Pre weekend

Had some international interest for the y1, but would *really* prefer to keep it in Australia......

HEH! Can't for the life of me remember where I stole that smiley from, but I always use it

The y1 DAC sale has been fully split from this post. It can now be found here.

The amp is now sold. The DAC is still available here. Thanks for looking!

Less than the total cost listed in the BOM.
