Direct thermal power dual triode cathode used in A1, AB1 amplify.
2A3C 2A3B structure is similar to the tube, use of the 300B-98 of the glass, the die using a three-mica fixed, it’s a good shock resistance, and 2A3B, like sweet music is smooth, rich layers of small and medium power HIFI preferred Sound of its shape resembles 300B-98 is even more wonderful music while enjoying access to the visual enjoyment. 2A3B/2A3C two mutually alternative, the Shuguang of the next two years are the highlights of the product.
2A3B is the Shuguang of a newly developed audio transistor, which uses a single-screen high-carbon alloy anode and a new spring hook filament, the anode dissipation rate than the Shuguang of the dual 2A3 nearly 5W, single-tube output can reach 6.5W, high vacuum exhaust, is a fine audio tube. It sounds better than dual 2A3 is more delicate, more powerful output. It uses a high degree of T16 through the glass type, it is slender and wealth is undoubtedly a good choice bile extremely lovers
