CLASS A AMPLIFIER MODULE BASED ON JLH 1969 IN BEYPORE

Class A Amplifier  Board 10-15Watts JLH1969  PCB Assembled (TIP2N3055) This is an assembled, adjusted and tested amplifier boards of the classic John-Linsey Hood 1969 class A amplifier. While JLH 1969 is a simple design, it is still one of the best transistor amplifier known manifested by clear sound and dynamics. Features:   1. Double-sided, thick copper PCB. This is doubled-sided so the copper pad and tracks ensures better conductivity,low loss and better layout reliability and durability is greatly enhanced by plated-through hole (PTH) process. 2. High quality transistors used on both small signal and power stage. 3. High quality electrolytic capacitors. 4. High quality PCB with roller tinned for good solder-ability. 5. High quality polyester film capacitor for audio coupling. 6. Use of TIP transistors ensures easy mount-ability on larger heatsinks. 7. High value capacitor at output ensures low frequency roll off and DC blocking ability.  Specification: 1.Operating voltage: Single supply DC 12V-26V (corresponding to 9-18V transformer) 2.Output sound power: approx 10-15Watts RMS 3.Sensitivity to be higher than 83db 4. Adjustable quiescent current between 0.25 Amp-1.5A, recommended 0.6Amp.
