The standard standard tube of CP6V is: Dawning 5Z4P*1 Dawning 6N8P*2 Dawning 6p6p*4 Dawning 6J8P*2
Power tube current adjustment device
The classic series CP6V is a compact 6v6 push-pull integrated amplifier. It belongs to our company and is the earliest and most mature classic low-power push-pull with antique shape. The whole machine uses 2 Chinese Dawning early 6J8P to be connected to the middle U triode to do the first stage amplification, 6J8R (6SJ7 house a high-gain pentode universal model, the sound is loose and naturally has the jumping power, in many ancient machines A large number of use; 2 China's early Dawning 6N8P (6SN7) to do long tail reversal amplification, this circuit distortion zjKgg power; 4 Dawn 6V6 for power output, fixed hemiplegia mode, power tube current meter display, monitor 4 power at any time The working current of the tube is simple and user-friendly. 1 early Chinese 5Z4P is used for rectifying buffer. This machine is designed to facilitate the operation of small sound stars in the bedroom. 6V6 triode is installed. This circuit can be obtained with the standard quadrupole switching circuit. Delicate sound quality. The backlight head on the front of the case can be used as a level display for each 6V6 current display.
The whole machine uses a power transformer with a capacity of 150W. The output transformer is an open structure horizontal installation with a power of 15W and a low leakage inductance design. The circuit uses a standard 4-pole connection method. When the output power is 10W, the distortion is less than 1%, and the index is good. Other key device potentiometers use ALPS blue enamel boutique, coupling capacitors all use Ben Nick silver foot metallized polypropylene capacitors, Taiwan custom tungsten wire backlight ammeter
The sound of this machine: loose and natural, medium-frequency rich, completely classic and old-fashioned, low-frequency relaxation, strong bounce, high-frequency slender and true, suitable for vocals, strings, Chinese folk music performance, moderate output power, low distortion, easy to match with common speakers .
Equipment m with instructions: input impedance 100K, three sets of signal input selection, easy to connect CD, computer player and FM radio, this machine is suitable for matching bookshelf or floor-standing audio with sensitivity greater than 85DB is not recommended to drive large-diameter aprons above 8 inches Non-paperboard low-frequency speakers), for small-caliber bookshelf speakers, full-range speakers, low-frequency thin and thin antique horn speakers have very good performance. The output impedance of this unit is 4 ohms and 8 ohms. The 6 ohm speaker should be connected to the 8 ohm output terminal. The maximum output transformer secondary winding is used.
