About us

Welcome vintage audio lovers!

Since 2019 when I lived in Spain I have been designing and 3D printing speaker terminal upgrade kits. At first they were only for personal use, and then I started making them for fellow members of the AudioKarma forum. A few years ago I started selling my small selection of kits on eBay. Since 2024 I have had more free time started to actively create new kits and refine existing ones.

I research vintage audio, design kits, 3D print and assemble kits, write instructions, and fulfill orders all from my small workspace in Portland, Oregon. This is a one person operation and I don't plan to change that. I very much enjoy researching vintage audio, designing, refining, and producing kits, and supporting customers. It is really satisfying to help keep vintage audio equipment working, relevant, and most importantly out of the landfill.

Please feel free to reach out with questions, comments, or to request a new product!

    Excellent product. Easy to install and perform exceptionally well. The price point is extremely good and the written instructions are well done. Shipping is nearly immediate and I had the jacks installed and running in four days from placing the order. I highly recommend this product. It brings vintage gear into the world of 21st century high end speaker cables like Cardas etc. well done

    Items arrived as brand new condition as described and look to be of excellent quality. They are just what I was looking for and fit perfectly. Buy with confidence if looking to upgrade your receiver’s speaker posts.

    Only complaint is the plastic piece is .015" wider than the opening in the Harman Kardon amp , thus the terminal strip mounts in a slightly bowed position which causes the outer terminal studs to bend toward the 2 inner studs. The stud spacing is already very tight and if the person hooking up the speaker wires isnt careful, they may find the wires become shorted.
