Product Overview
Motorola 6S185B96 - a file card pack of ten 1.5 Megohm, 1/2W, 10% tolerance carbon composition resistors. Packaged on a printed card with R.E.T.M.A. color code chart and National Motorola Communications Service branding, printed in the U.S.A. The card tab is stamped with catalog number 6S185B96. You get ten resistors per card.

Applications
- Restoring an antique radio where original carbon comp resistors have drifted out of spec - drop these in and keep the circuit period-correct
- Tube amplifier repair where the vintage tonal character of carbon composition matters, not just the ohm value
- Ham radio restoration work on older transceivers and receivers requiring period-appropriate components
- High-energy pulse circuits where carbon composition's pulse-handling characteristic is preferred over film types
- Builders and tinkerers working on scratch-built vintage-style projects who want authentic NOS components rather than modern substitutes
Frequently Asked Questions
Are these carbon composition or carbon film resistors?
The research confirms carbon composition. The brown axial-lead bodies and the era of Motorola National Communications Service packaging are consistent with carbon comp construction.
How many resistors are in the pack?
Ten resistors per file card.
Why use carbon composition instead of a modern metal film resistor?
Carbon comp resistors are preferred in vintage restoration work for period-correct appearance and the tonal characteristics that tube amp and vintage radio enthusiasts specifically seek out. They also handle high-energy pulses well, which matters in certain flyback and power supply circuits. For low-noise or high-precision modern circuits, metal film is the better choice - these are built for vintage work.
What is included in the purchase?
One file card with ten 1.5M Ohm 1/2W 10% carbon composition resistors.
A Motorola file card from the era of tube radios and R.E.T.M.A. color codes - the resistors are still on the card, still reading spec, still waiting. Your restoration project just got ten fewer parts to hunt for.
