Use of full coupling output transformers gives the 845 a more powerful drive capability, easily responding to the negative repellent 845 J5; the noble 845T is energy efficient. The sound is also tbi early dawn 845 splendid extravagant.
Double 5Z4P rectifier per block, The delay feature of the side heat pipe is the valuable 845 power biliary power supply.
The 845 and 2A3 are all DC powered, with a voltage regulator circuit, which makes it stable and low noise output is meager. The circuit easily uses the front-end CD without adding the pre-stage CD.
True natural output every detail 845 tube 1000V B pressure application, let the power of the last stage less than 5% distortion When it reaches 28w In the same type of A1 class 845 circuit at one end, the output reached the maximum.
Intermediate frequency quiet and heavy, high frequency and meticulous, has some reserve power, driving force is obviously better than 300B. It can be said that this is a relatively demanding speaker and music Software very adaptable HIFI single ended amplifier.
Equipment matching instructions: input impedance 600 ohms (unbalanced) 150 ohms (balance), this is appropriate to match a sensitivity higher than 86DB plus speakers. Output impedance 4Ω and 8Ω square ohms should be connected to the 8Ω output terminal.
All system have 3 levels preamplifications,
The first made by two special preamplification transformers, and then 12at7, and then 2A3 for driver+driver transformers, offer 1.5 upgrade gains to driver 845 tube, make a max power for 845 power tube
845 and 2A3 use DC filamment alimentation
Many other updates for the new version, description will be updated it later soon
