LM4780 Gainclone Amplifier

LM4780 gainclone amplifier with a design similar to the National Semiconductor BPA-200 (Bridge/Parallel Amplifier) which uses 4x LM3886 per channel and an input buffer. The total effect is (2x LM3886's paralleled amplifiers) 2x Bridged and should give approx 225 watts into 8 ohm and 335 watts into 4 ohm speakers when used with a sufficient power supply.

Build Accurate LC Meter and start making your own coils and inductors. This LC Meter allows to measure incredibly small inductances making it perfect tool for making all types of RF coils. LC Meter can measure inductances starting from 10nH - 1000nH, 1uH - 1000uH, 1mH - 100mH and capacitances from 0.1pF up to 900nF. The circuit includes an auto ranging and reset function to make sure the readings are as accurate as possible ... [more]
