Hi Guys,

NTD1 PCB and Matched quad:

I had this board set aside as a spare for myself, but I now have a V2 board to take its place. There is no real difference between V1 and V2, but V1 will only support Acko and BII.

This is genuinely the last one that will come available in the foreseeable future!

Completely unused with a brand new quad of matched mosfets.

Firstwat F5 Power supply and three-channel PCB

This is a Firstwatt F5 PCB that I designed a while back. It's a stereo PSU and two channel power amp. There is also a third channel included in case you mess up one of the others. These work exceptionally well, and served as my main amp for many years.

They are brand new, unassembled, and ready to be built!

No support for these, and anyone who knows how to read a schematic will be able to figure them out easily. There is also a thread on here somewhere with more details.

National LME49600 Eval Board

I purchased this when I was evaluating the buffers for The Wire series of headphone amps. These eval boards are VERY expensive brand new, and represent the manufacturer's best efforts at showcasing their parts. This one is in great shape, and fully functional. Working volume control, battery power option and output jack. Input jacks were removed, but they sucked anyways.

The Wire Bal-SE Fully Assembled

Exactly what you think it is :)

It's my personal unit, and it was fully assembled by your's truly. I use the BAL-BAL and SE-SE regularly, but don't have a need for this one.

The Wire PSU Fully Assembled

This was the PSU I used with the above amp. Priority will be given to anyone wanting the pair.

The Wire SE-SE Rework boards

Two final remaining reword boards

The Wire SE-SE boards

Three remaining SE boards.

The Wire PSU PCB

The only remaining PSU board.

Twisted Pear Volumite

Used, fully assembled with "Firmware". Fully functional.

IRF IRAUDAMP7S Eval Board

This is a genuine IRF eval board. It has upgraded output inductors (ferrite core) and upgraded caps.

I let a friend of mine borrow it and it came back with a blown output stage and I believe damaged drivers. It would take some work and knowledge to fix, hence the low price. I don't have the time, and I can't stand listening to class D amps :) A full schematic is available.

Audio Power DPS-500 Power Supply, 120V input

I have a pair of these that were used for lab testing. One unit failed during power up transient testing, so I stopped testing.

The failure is not catastrophic, but something in the remote power up circuitry went haywire and smoked.

The other unit is good and still working normally.

Both units look like they have been hand modified, but did come directly from Audio Power. As a result, they are being sold "as is".

Audio Power DPS-400 Power Supplies, 230V input

These are also lab test units, but both units are working just fine and perform as expected. 230V input only!

One unit has a cracked PCB where the standoff was mounted, but it does not affect functionality.

Sold "as is"

Audio Power DPS-600 Power Supply, 230V input

Yet another lab test unit, fully functional, and ready to go. 230V only, and again, sold "As is"

Audio Power PBT-2 regulator board

Semi functional regulator board. This was intended to be used with the DPS-400 for additional filtering. The regulators for the HV taps don't seem to be adjustable. I think it's just a circuit error.

Sold "as is"

The Wire LPUHP fully assembled low power amplifiers

These were my babies for the past year and a half. I used two pairs in my main system and one pair on my PC. They are my favorite amps, and likely the highest performing power amps on the planet.

I now have the "production" versions in house so I'm selling these.

They were all fully assembled by me, and are in perfect working condition. Two pairs are balanced input, and one pair is SE input. They include the transformers and fully plug-n-play. Add a fuse, plug them in and you're ready to go.

See here for details:

M-Audio 1010LT PCI Sound Card

I used this sound card for loudspeaker measurement and crossover development with Sound Easy and UE. It's a very good quality card, and works perfectly. I recently upgraded to something a little fancier so I no longer need this.

Comes with cables.

Vifa TC9FD-18-08 3.5" Fullrange Drivers

My favorite little fullrange. I built a huge line array with these, and I have a few spares.

Kuribo:

I got your note, but your email address is either old or non-functional as I got an un-deliverable notice when I replied. Try PM instead.

Your questions are mostly answered above. Make sure to read the link.

gaborbela:

I'll get you a quote for shipping tomorrow. These are absolutely 100% genuine (straight from ON Semi). If they weren't I wouldn't be selling them :)

Cheers,
Owen

gaborbela:

The parts you're looking for are small and light enough to fit in a lettermail padded envelope, so shipping would be $3.75 to Toronto.

The total weight has to be below 500g, but even with 20 TO-3 packs and 8 TO-247 packs you're still under that number.

I also made a mistake in the list, so to clarify, here's what I have left of the parts you asked for:

MJL4302: 4
MJL4281: 6
MJ11033: 25
MJ11032: 25

Please specify exactly what you want in individual parts (as above) and I'll get you a total.

Cheers,
Owen
 
I was planning to use the LLPUHP to drive the adapter for a set of Stax electrostatic headphones but a Stax amp just presented itself. Not sure which set up will be better but I think I will pass at this point on the LLPUHP and try the Stax amp. If it doesn't work out, I will in line when the commercial product appears.

Sorry for any inconvenience I may have caused....
