Carbon composition resistors can be found from almost all amplifiers made between 40-70´s. Many believe that those are one part of warm sound old amps produce.
# ½ watt # -55° C to 125° C operating range # +/- 5% tolerance # 350 V working, 700 V overload # Low inductance # Low capacitance # Better pulse endurance characteristics than film type resistors # EIA color coded # 0.38" long x 0.41" diameter
