I'm selling off a few projects I've had laying and collecting dust for some years now.
If you don't finnish a project in 6 months, you never will...
Its a matter of space too, I've collected so many PCBs and components for projects that its starting to get ridiculous.
-------
Ok, first up is 4 PCBs of YAHAs.
It is a simple tube headphone amp that can be powered by a simple 12vdc wallwart or a battery. Very simple!

Input caps on the populated boards are 0.47uF polypropylenes, this amp requires output caps too, its electrolyts bypassed with Wimas on the underside of the board.
Board #1 is the one in the picture, it is fully populated.
Board #2 is as #1: fully populated
Board #3 is almost fully populated, its missing one of the high watt resistors feeding the heater of the tube. It also misses a tube socket.
Board #4 is just the PCB, never touched.
I will include 5 pcs of JRC4556 Opamp.
Next up is the Millet hybrid boards.

1 of them is populated as in the picture (all resistors and caps are installed, and some other things.
The other one is just the PCB
Price for the YAHA boards are €15 + paypal fee + shipping
Price for the Millet Hybrids are €15 + paypal fee + shipping
If buying both the YAHAs and Millets: €25 + shipping
PM for shippingcost to you. I'm in Sweden.
