03 / Repair bench
Vintage hi-fi & audio
Turntables, cassette decks, receivers and amplifiers: cleaned, re-capped where needed, aligned and channel-tested. The kind of work that brings a dead deck back instead of landfilling it.
Electronics & computer repair
Diagnostics, board-level fixes, recovery and refurb on computers and consumer electronics. Diagnosis first, a quote before any work, no surprises on the invoice.
We repair nearly everything we sell, lab instruments and pipettes included. Ship it in or drop it off (Frankford, Philadelphia). What we repair →
04 / For businesses: fleet services
The same automated bench, as a service: bulk hardware testing with per-serial reports, bulk imaging and provisioning (Windows or Linux), custom golden images, NIST 800-88 aligned data wipes, and network gear reset and reflash: for resellers, schools, and offices with a pallet of machines, not one. See fleet services →
05 / Also: AI software instead of SaaS
The day job behind the bench: I build AI-powered software for small businesses instead of another SaaS subscription, plus platform and DevOps work when that's the actual need. Separate from the shop, same person. See the consulting work →
