4 homemade tube 6J4P, and circuit parameters were re-set, 300B 845 tube amp pushing enduring. And installation of a voltage delay protection, boot high pressure pipe would not have impact on the formation, so that the tube longer. 3,300 B with the ideal combination of tube 845, which is 845 300B push sought after by many knowledgeable enthusiasts ideal combination of luxury by many large manufacturers tube amp used as a real tube amp enthusiasts know that the " pre- aloud level after output "that is, tube amp sound quality is determined by the previous level, power is determined after the class, and the section of the machine SG-845 machine preamp tubes with antiques from abroad is the best sound quality domestic 300B tube as before class, after class is great 845B by the power for the power tube, pushing Acoustic speakers definitely not a problem. So in full compliance with " pre- aloud, after the class output " this truth.

Overall just use 300B 845 300B push for a guarantee of its quality , the use of its power output 845 were protected. 845 IF charm while moving, human voice very attractive, but also the essence of this bile.

In particular this machine after upgrading from five times. Almost to the perfect combination. 300B and 845 can be described as a combination of strong combination of complementary advantages ; swords together arm, the world first , fever preferred amplifier. 4, this paragraph is characterized tube amp pushing many models fit speakers, like the vocal chords music bookshelf speaker can choose, if you like, then you can choose the symphony floor speakers. 5, on the two sides of tube amps have two current meter is designed for timely monitoring machinery working condition, protect the machine work is in the best condition.

(Generally only high-end machines have ammeter) enthusiast knows tube operating at its ideal operating point is very important, if not working in the ideal operating point, even if the tube is not even the best advantage, sound serious distortion. The ammeter is necessary because it protects the tube work in an ideal operating point, to protect the tube amp sound without distortion. The role of these two currents instruments are: a, used to adjust the balance of left and right channels, left and right channels are constantly monitoring the output sound the same size, and if not, the customer can use this instrument instruction to make their own adjustments (Do not open the chassis, with the word screwdriver can be adjusted, it is convenient).

Third, tube limited life, and with the longer screen flow may be getting lower and lower, the output power and the quiescent operating point will change, then through this instrument display to adjust the quiescent point, make sure your will power and timbre degraded because of the aging of the pipe, and always in top working condition. Standard configuration is to use the dawn of 845, the dawn of the 300B-98 tubes. 1 X Tube amp electron tube Amplifier.
