This dual transistor stereo amplifier module TTC5200 is of a design reproducing a proven pattern which marked the sound of the glorious years of the HIFI of the 1970s. Here it is in an updated version with transistors and modern components.
The clean layout allows modifications and upgrades for experienced "DYERS" who are familiar with this type of schema. An amplifier of simple design in "quasi complementary" design with two Toshiba NPN bipolar per side that offers a sound of a large joint without the usual defects of crossing crossover with several transistors.
Thee assembly will be simplified for fixing on aluminum heatsink computed accordingly with pre-drilled holes (optional).
Un amplifier with melodic, warm, structured sound, reserved for connoisseurs possessing high efficiency speakers .
This class A amplifier, due to its operation, generates heat. The power components should be of high quality to walk properly over the long term.
It is therefore intended for persons with good knowledge in electronic assembly to measure the rest voltages for example.
Provide a transformer and its power supply card capable of delivering between 12 and 28V DC (see accessories).
If you intend to use this amplifier on vinyl phenolic membrane compression chambers ortweeters with low permissible power, provide an anti-POP timer for your speakers.
- AT: VCC input from 12 to 28V (VCC + and GND -)
- B: VCC input of 12 to 28V (VCC + and GND -)
- C: Speaker output (GND = ground, OUT = plus terminal)
- D: Speaker output (GND = ground, OUT = plus terminal)
- AT: Stereo analog line input with GND common ground (IN left and IN right)
Quiescent current can be adjusted with W202 trims, and output bias with W204 ones.
