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!

- n***9 (142)- Feedback left by buyer.Past monthVerified purchase12/20/2024 placed my first order for 2 sets of these. On 12/18/2024 I placed an order that resulted in a refund. I recall some communication that I needed to order two sets, which I thought made sense because I was aware the unit has two sets of four speaker terminals. So I ordered and rcvd the two sets. Apparently I still didn’t account for the second set of four speaker terminals, because on 8/22/2025 was told I didn’t provide enough to complete the job. I’m still confused… thanks!
