Regarding the matching, all of our tubes are matched in the factory production workshop. The matching is accurate (not all tubes have been matched). We have the conditions and advantages to match multiple tubes (four, eight, ten) according to customer needs. The parameters of the two tubes are the same)
A3C uses a 2A3B slender tube core with a double-layer mica sheet structure. It is fitted with a high-transmittance 300B glass bulb, a new spring filament is fixed, ultra-high vacuum exhaust, stable and reliable, and looks exactly like 300B in appearance, but it There are many lovely details. The double-layer fixed mica sheet makes the inside stronger and controls the generation of the microphone effect. The transparent quartz glass shell is decorated with pure gold pins, which is very powerful, and the favorite or unique Musical expressiveness
The direct-heated cathode mid-power double triode is used for A1 and AB1 amplification. The original 2A3 produced by Sugon are dual-pipe parallel connection, and the pin connection has 4 pin and 8 pin connection methods, which is called the small "300B". Sugon first launched 2A3B in May 2004. 2A3B adopts a single-screen design. The filament adopts a high-strength spring hook structure, which overcomes the method of fixing the original 2A3 filament by using top mica. The original structure of 2A3 is Due to the thermal expansion of the filament during operation, it may loosen the filament and make the output unstable. The new 2A3B has no such situation, and the output power has also been increased. Moreover, the upper and lower mica sheets have adopted anti-leakage design, which greatly solves the leakage noise caused by 2A3. Its stability is very good, and its workmanship is exquisite, which has exceeded Russia. Similar tubes; currently, its sales are increasing month by month.
2A3C is a tube type similar to 2A3B. It uses a 300B-98 glass envelope. The core is fixed with a three-layer mica sheet. Its shock resistance is good. Like 2A3B, the music is sweet and smooth, with rich layers. It is a medium and small power HIFI. The choice of audio. Its appearance is exactly like 300B-98, which makes people enjoy visual enjoyment while enjoying wonderful music. The two tubes 2A3B/2A3C can be substituted for each other, and they are both products that Shuguang focuses on.
