Thd Hot Plate 8 ohm

Hot Plate colors are related to their impedances. There are five different Hot Plate models: The 2Ω (gold), the 2.7Ω (green), the 4Ω (red), the 8Ω (purple), and the 16Ω (blue). To optimize tone and function, the impedance should be the same on your amplifier, Hot Plate and speaker cabinet.
