Item 14 – 6.5” Mpyre 65x Baltic Birch Subwoofer
I built this about 2 years ago to use with the small TC9FD boxes to fill in the region below 120Hz. It's a passive sub, no amp or crossover, intended to be driven by an active crossover and an external amp.
I showed this system at the last Ottawa DIY gathering, and driven by a full compliment of MPUHP amplifiers with a modified DCX2496 (also listed) it sounds far better than a system of this size or cost should have the right to sound. It would make an incredible computer audio system, or a dedicated system for small to medium size room.
That setup can be seen here:

Item 15 – Vifa TC9FD-18-08 Baltic Birch Transmission Lines with BSC
I built these specifically to see how much you could get out of a single TC9 driver. It's a properly designed TL and the height is intended to put the driver at ear height when sat on a desk. These are intended to be used without a subwoofer for nearfield monitoring.
The feature full BSC and measure very flat. Bass extension is pretty solid down to about 100Hz.
These are in very good shape, but unfortunately one of the boxes suffered some tearout on the front when I was routing the front TL port. BB has a strong tendency to do this if you approach it the wrong way, or use a less than perfect router bit. It could be filled with a color match wood filler, or just covered with veneer or painted. The low price reflects this issue. Functionally these are perfect.
I included a few pictures of the insides, but both boxes are finished and sealed up.

Item 16 – Vifa TC9FD-18-08 Baltic Birch Ported Boxes – No parts
These are two nearly complete small ported boxes for the Vifa TC9.
I built these as a second pair when I was building my main set. The sides need to be glued on and chamfered, the ports mounted, and then just finishing touches. If you want to build a small set of speakers on only own a router, this would be a great way to go.

Item 17 – Analog Devices (ADI) AD1955 DAC Development Board
This is a fully functional (and very good sounding) DAC. Just needs a chassis.
It's an official ADI eval board which originally cost $550. These are great platforms as the actual DAC manufacturer sweats all the details of the design to make sure their DAC sounds as good as possible and measures according to the datasheets. In that regard, no cost is spared on parts. All output op-amps are AD797 and there is full balanced output and SE output which can be used concurrently. Input is TOSLINK, SPDIF, or AES/EBU. This board requires an external +/-12V supply.

Item 18 – DIY Pass Labs Aleph 2 Amplifiers – No chassis
These are a fully functional and complete/tested pair of DIY Pass Labs Aleph 2 amplifiers boards. You just need to add transformers and heatsinks/chassis. Also optional are two large chokes for the PSU, or you can use power resistors or just bypass this option. I used a massive pair of 12AWG Alpha Core 2.2mH foil inductors.
All parts are top of the line. Elna "For Audio" 10,000uF 63V x 12 for PSU, Caddock or Vishay resistors and Elna Cerafine for signal sections.
These were used in a custom CNC chassis (also for sale) along with two massive Plitron 1000VA toroidal transformers. I've parted these out as the chassis are not complete, and far too heavy to ever ship anywhere.
All fets are mounted to an aluminum bar which needs to be mounted to a heatsink. Same applies to the rectifier diodes.
I have included a picture of the complete amps for reference, but please note that this listing is only for the complete circuit board shown.

Item 19 – DIY CNC Monoblock Class A amplifier chassis – Black
These are a seriously heavy duty all aluminum CNC chassis for pretty much any high power Class A amplifier. They were used for an Aleph 2 and can dissipate roughly 350W continuously per channel without breaking 45C.
I built these myself back in college, in the days when electricity didn't cost an arm and a leg in Canada, and our place was heated with electricity in the winter anyhow. Those were the good old days... I couldn't afford to run these today.
The top, bottom and faceplate were all CNC machined from 1/2" aluminum plate, and then anodized black professionally in Toronto. The heatsinks are from Aavid Thermalloy and were custom cut and anodized by them.
Everything is held together with metric hex bolts and aluminum L-channel.
There are no back panels, as I never got around to having them made.
I think the heatsinks alone cost more than what these are listed for, nevermind the cost of the rest of the aluminum and the 100+ hours of work on the custom CNC parts.
Please note that I included a picture of the completed amplifiers, but this is for two monoblock chassis only with all parts except the back panel.

Item 20 – OPC NTD1 V1 – personal unit, fully tested – matched FETS
This is a complete NTD1 V1 with heatsink and transformers. All you need to do is drop on a TPA BII, BIII, or Acko DAC and you're off to the races.
This was the unit used for all measurements and testing. It also has a very well matched set of FETs.
Please note that the AC inlet will be removed for legal reasons. The DIYer who buys this is responsible for implementing the AC input safely with a fuse and any other necessary legal requirements.
If you always wanted an NTD1 but didn't have the skill to build it, then this is for you!

Item 22 – OPC LME49830 V1 – Fully Assembled and Tested
Only one is shown in the pictures, but there are two which are being sold as a stereo pair.
These are tested and working, both are configured as DC coupled SE inputs.
I will remove all wires and clean the solder from the pads. I don't have time to make any changes to these, so as-is only.
Buyer should be prepared to check everything over and go through the proper bring-up procedure outlined in the user manual I wrote for these.

Item 23 – OPC LME49830 V2 – Fully assembled and tested
This is being sold as a single channel as that's all I have on hand. I do still have bare boards left and I am happy to throw one in with this. I also have an extra pair of FETs I can include. Sale price includes all this.
It's tested and working, and currently configured for DC coupled balanced input.

Item 24 – DIY Pass Labs Aleph Ono Phono Preamp
This is a complete kit from Nagard Acoustique that I build quite a while ago. Full dual mono design all the way back to the outlet. Separate PSU and signal chassis. Umbilicals are standard XLR and I will include them.
Takes SE inputs for either MM or MC. Balanced or SE outputs. Everything works perfectly with very low noise and excellent sound.
Everything is mounted in older prototype chassis, and the heatsinks are just for show in this application
The chassis are not in the best of shape, but they get the job done.
Please note that these are being sold AS IS, meaning they are being sold as a partially completed DIY project. It is the sole responsibility of the buyer to ensure they adhere to local laws regarding safety for the mains inlet. These are not UL, CE or CSA certified. Please make sure you as a buyer are aware of the implications of this.

Thanks Daniel!
Looking forward to getting there! It's -12C in Ottawa right now, and the whole family is stressed to the limit trying to get everything ready in time for the move! It'll be nice to get to SD and start settling in
I'll have to touch base with you when I get there to see if there are any local events or gatherings.
Regards,
Owen
