Default Loads of DIY Stuff for Sale! Amplifiers, transistors, IC's, heatsinks, XFMR's etc!!!

Hi Guys,

I've come to that point where I've been doing this for so long that I have cabinets full of finished, half finished, and un-started projects.

I need to clean up, and I need to put some money towards my current speaker project, so this is an "everything must go" sale of all the audio goodies I'm not using or never had the time/will to finish.

I'll be posting items here in groups, along with pictures. I might not attach a picture of every item listed, but if you want to see anything just send me a note and I'll send you a picture with details.

Expect to see:

Finished Amplifiers - I've got an ST-70, and some other custom tube amps.

Amp kits - all the parts you need to build an amp, but not fully assembled

Amplifier PCB's and heatsinks

Loads of IC's - Chip amps, op-amps, etc...

Loads of transistors

Transformers

Capacitors

Drivers

I'm still debating whether or not I should sell my DIY Aleph 2 monoblocks, and my cherished pair of Lynn Olsen's Ariels. These are big ticket items that I put countless hours into, but if someone can make good use of them, and is willing to put up the money, then I would probably move them. Details will follow, or contact me if interested.

As always, all items are available for pickup in Ottawa, or I'm willing to ship anywhere in Canada or the USA. Only smaller items for overseas shipping.

Most prices are at most half of retail, and sometimes much less than half. If you really want something, and you think my price is too high, then feel free to make an offer. If you're buying several things, we can certainly work something out.

The first list up will be IC's, so here we go!

Cheers,
Owen

I might be interested in the bigger transformers and those TO-3 transistors. Could you give a little detail on those items?

thanks.

I have the following PCB's:

Moskido

Single channel, fully integrated class A amplifier with the Aikido tube front end. You can build most of the Moskido variants on these boards with minimal changes. I have full documentation and parts lists.

See details here:

Moskido PCB's For Sale - IRF Type

Asking $20 per board, which is way below what it cost to have them made. I have 5 pairs left.


Firstwatt F5

I have single channel boards left, and a few power supply PCB's. These are intended to go together as one power supply and two single channel boards. Comes with parts list, and I have several spare parts to make kits if people are interested.

This is what I'm presently using as my main amplifier, and I can't say enough good things about it. By far my favorite amp.

Single channel boards - $10 each and I have 9 left
Power supply - $20 each and I have 2 left

I have enough parts to fully build all these boards, or make kits for those interested in building their own. If you want prices, let me know.

See pictures of F5 boards below:

Default More PCB's

I have a full set of home-made boards for a BZLS Preamp with a Relay based volume control. These are partially populated, and are being sold in "as is" condition. If you're clever, you can make yourself a great little preamp with these. They work perfectly when fully built, and I used them for a year while I was building my good version.

$25 takes the whole lot as pictured. The relays alone are worth much more than that.

There are two power supply boards, two preamp boards, two relay volume control boards, two input select boards, and one relay power supply / microcontroller board.

NO SUPPORT, NO DOCUMENTATION - DON'T ASK. If you can read a schematic, you can get these working. See the BZLS article on PassDIY for details.

Pass A40 amplifier boards:

Another set of home-made prototypes for an A40 amplifier. See the A40 article on PassDIY for details on the schematic.

These were designed to have the transistors mounted off-board, and there are screw terminals for all connections. I used TO-3 packs mounted in large heatsinks when I was using these.

These boards are complete and functional, so all you need is the power transistors which are available above.

Same rules as above apply to these: no support, no documentation.

$25 takes the pair.
