Илья Р.27 February 2023·Show originalArrived quickly, a week and a half ahead of schedule. Without damage. The boards are neat. Made well from the outside. But the flux is not washed from below. Although the soldering is good. Now about the transistors of the output stage. It seems that they were soldered from the equipment of Phantoms shot down in the Vietnamese jungle 50 years ago, and then for another 50 years they were driven in a draft cart through the same jungle right up to Shanghai. This is expected, since the board descriptions indicate that second-hand transistors. But they're very scary. For the rest of the moments I will supplement after installation.

Hello. The amplifier is good, really a thing, sounds a little better than the early version of JLH 69. Quality boards, lead-free soldering, Rifa and wishai Ero film capacitors. There is a current imbalance of the original 2N3055 output transistors, but this is not critical, their performance is also good. Sound source used DVD player, budget acoustics dlialog w204.
Show moreAdded 23 March 2023·Show originalI put the boards, powered it-25 in. current for each transistor 500 Ma is recommended-18, but more can be done. The boards are made and sealed professionally, taking into account safe soldering and further upgrade. emitter resistors for convenient current setting Voltage drop on them, you can put on 0.1 or 1 OM. I still selected the output transistors in fours for myself in terms of gain. The sound has a sense of character, greater stereo separation, wider bandwidth, and enough sound power.

Description
NOTE:
This is a pair of finished boards, the set board current is 1A (each tube) This configuration is thermally conductive aluminum (not a radiator), which is convenient for customers to connect large radiators; Please do not leave the power on for more than 10 seconds, otherwise the power tube may be burned HOOD JLH2003 is an upgraded work after JLH1969, from JLH1969 single power supply to OCL dual power supply, and parallel management, the maximum output power reaches 22W (at 8 Euro load) Compared with the single power supply of JLH1969, the output frequency response curve of JLH2003 is flatter The circuit magnification is 13 times, suitable for making power amplifier and ear amplifier.Parameters:
To achieve the best sound quality, the static current of each tube is set to 1A, that is, the voltage difference between the two ends of the emitter cement resistance (0.1R) is 100MV 22W pure class A amplifier, the heat is relatively large, please pay attention to heat dissipation Recommended input voltage, plus or minus 18VDC (can be obtained by rectifying with dual 15VAC-200W transformers) Single-sided PCB 15.6 * 7.4 * 1.6MM, 1OZ copper
