Overview
The Motorola 6-6430 is a vintage carbon composition resistor pack featuring 10K ohm resistance with a 1W power rating and ±10% tolerance. These axial-lead resistors were manufactured in the United States and represent the classic design era of discrete electronic components. Carbon composition resistors remain popular for vintage radio restoration, amplifier repair, and authentic electronic reconstruction where original component specifications must be maintained.
Key Features
- 10K Ohm Resistance Value — precise 10,000Ω nominal rating for signal conditioning, biasing, and load applications
- 1 Watt Power Rating — suitable for moderate power dissipation in audio circuits, bias networks, and general analog applications
- ±10% Tolerance — standard tolerance for carbon composition construction, acceptable for non-critical signal path applications
- Axial Lead Configuration — traditional through-hole termination for breadboard, point-to-point, and PCB mounting
- Vintage Authenticity — original Motorola manufacturing ensures authenticity for restoration and preservation projects

- Restoration projects requiring authentic Motorola component replacement
Replaces / Drop-In Replacement For
- Original Motorola 6-6430 carbon composition resistor packs
- Generic 10K ohm 1W carbon composition resistors in vintage applications
- Verify compatibility with your circuit schematic before ordering — carbon composition tolerances and frequency response differ from modern thin-film resistors
Works With
- Tube-era audio amplifiers and receivers
- Vintage radio equipment (AM/FM receivers, shortwave sets)
- Classic test instruments (multimeters, oscilloscopes, signal generators)
- Point-to-point hand-wired circuits and early printed circuit boards
- Analog signal conditioning and biasing networks
