Features:
1; Refer to the dartzeRRel HB-108 circuit , using 3 pairs of A1943 / C5200 power tubes.
2; no feedback circuit design, high and low frequency response extension is very wide, good resolution, three tube output control super .
Product Name: HB-108HiFi pure after the power amplifier board, test good (1943/5200 version)
Product Outside Size: Length 192MM * Width 84MM * High 61MM
Input voltage: DC DC 45-0-45 (available in double 30-65V)
Output power: 200W + 200W 8 ohms, 4 ohms: 300W + 300W ( 2.0 channel = 2 PCS )
In the DC positive and negative 63V power supply, in 8 Europe can get 200W of output power, each board transformer power 300W or more
Frequency response: 10HZ-30KHZ
Power amplifier board of the quiescent current is higher, a board heat sink at least 2KG above, do not add a good heat sink before the power board should not pay attention to, or will be damaged
