The kit itself was complete (all parts were there), but the resistors were poorly marked , so a DMM is a must (for the capacitors as well). Assembly-wise , I'd say it's for the advanced beginner / intermediate level electronics hobbyist. There was no schematic included, and the documentation on the Thaikits website was not helpful. The problems came when trying to power the board up. I did not opt for the accessory power supply, so I tested the completed board using two linear supplies (Rigol and Agilent) with isolated (!) outputs , set each at 15 VDC and tied them in series, to get separate + and - outputs w the series interconnect tapped for the "0" volts. A ground connection from the scope to the "ground" tie on the PCB is necessary. With this set-up, the curves were way too noisy for reasonable gain measurements. To get the curves (from a 2N3904) in the picts, I ended up using two 13 volt LiFePO4 batteries tied in series which dramatically reduced the noise. As shown the old Tek 503 gave a nicer trace compared to the 2335, so the choice of scope also matters. It also helped to place a couple of ferrite beads onto "Y" input lead. the All-in-all, way cheaper than a used commercial curve tracer, but don't expect too much for the price. ### ⭐ Dont waist your time *by E***D on November 6, 2015* Does not work. --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.vu/products/71091967-transistor-curve-tracer-adapter-xy-oscilloscopes-2-ranges-bias-unassembled](https://www.desertcart.vu/products/71091967-transistor-curve-tracer-adapter-xy-oscilloscopes-2-ranges-bias-unassembled) --- *Product available on Desertcart Vanuatu* *Store origin: VU* *Last updated: 2026-05-15*
