## General Notes - [Build Guide](https://guides.diyaudio.com/Guide/F5M+Amplifier/29?lang=en) - ![[Pasted image 20260204154816.png]] - [Discussion Thread](https://www.diyaudio.com/community/threads/f5m-kit.408290/) - Use [Cardas Quad Eutectic Solder](https://www.cardas.com/supplies) for all audio work! - Note the end of manual regarding bias adjustment vs heat dissipation - Wiring - "I use red/black/blue for the +/0/- on split power supplies / 20-22 AWG stranded. UL1007 (300 V) or UL1015 (600 V) depending on the voltages in the circuit. Copper because the electrons don't care much about copper vs silver. For higher current connections internal to a chassis, I go up to 16 AWG. It's plenty of cross-sectional area and still quite malleable." - "I use the 22 and 24 gauge solid core for signal level runs and 18 gauge for power supply runs." - "24 ga for signals, 22 from the drivers to the output transistors, 18 in the power supply." ## Manual ![[F5M_DIY_AMPLIFIER_R1.pdf]]
