LM4780 Chip Amp Balanced Dual Mono-Block Amps Improved Bass and High-End Clarity
LM4780 Balanced Dual Mono-Block Amps Improved Bass and High-End Clarity
Purchased the dual mono LM4780 Kit Peter Daniels@AudioSector.com and received in the mail the other day. I’m excited, because the packaging of National Semiconductors’ LM4780 chip allows easy implementation of a bridge / balanced differential configuration (such as XLR / TRS) inputs from professional sources. Most of the equipment as “pro” uses XLR because it allows longer cable runs and offers a high degree of signal noise and interference suppression.

As the causes of the heat sink mounting surface to approximately 6 mm from the edge of the circle are fixed, assuming that the amplifier circuits mounted directly on the rails. This means that the leads of the transistors must be folded twice, so they are positioned properly, without a permanent mechanical stress in transistors. For high output transistors, the first corner a little closer to the plastic packaging than expected (in the wide part), otherwise the son of the rails or not to strike. Another possibility, which has the disadvantage that it weakens the structure, it is to grind enough metal in appropriate locations, to provide sufficient clearance. We have consciously rejected that option.

LME49710 High End Headphones Amplifier for Audiphiles
Kelvyn Shaw in England sent us a message with a link to his latest DIY audio project – a high-end headphone amplifier. The headphone amplifier with only high quality components and built around the National Semiconductor LME49710 high-performance operational amplifier Hi-Fi should be noted that costs 20 times more than a typical operational amplifier.

Suppose you were limited to three words, three words what would you describe your ideal hi-fi Sound? Seriously, think about that simple (but legitimate) question for a moment. Now ask yourself, “Do not be aesthetic?”. Many claim they do not, but I have systems that could have been attacked by an army of hammers that I do not live with them on a daily basis seem seen. Few music lovers believe that everything is sound and aesthetics are irrelevant.

The original Monster Jean Hiraga 8W class A amp, I wanted “The Monster” big brother build “20W Class A” amplifiers. After reading the construction, testing of Jean Hiraga 20W class A amplifier, and copies of old French magazine “L’Audiophile” I was interested to hear for me, as the monster sound like the big brother. I decided to build my latest version on the basis that I find as a “Super Class A 30W”
The original of Jean Hiraga Super Class A 30W amplifier circuit diagram and PCBs
In the past, I showed the original layout in the magazine article and the original driver transistors. However, due to the unavailability of the power transistors of origin, I opted for a more robust amp with Toshiba 2SA1943 and 2SC5200 pairs of complementary transistors. This change allows me to transistor voltage rail, which can increase the amplifiers deliver more power. The schematic for my version of Super Class-A, Jean Hiraga 30W amplifier.
