Description
DescriptionThis is a single-stage amplified OTL amplifier with class A single operation using a Darlington connection (so-called Tamarrington connection) between a 421A and a 2SC3857.The circuit is simple enough to memorize and is based on a tamarrington or super three-connection circuit on the Internet with a choke load instead of a transformer. In principle, it is a choke-loaded capacitor output OTL amplifier with 421A as 80 paras! The 421A operates at an RMS plate voltage of 20 V and current of 12 mA, which is about the same as if it were sleeping. The 421A heater is igniting at about 5.8V, the lower rated limit. Maximum output power: 4.9W/10? at the point where the waveform begins to be disturbed, increasing to around 7W as it is.Frequency response: 20 to 20kHz flat 10Hz -1.5db 100kHz -3dbGain: 3.5x VR position usually around 10 oclock becomes around 12 oclockNoise: Not detectable by oscilloscope, silent from SPShipping Fedex,DHL,Japan Post *For FedEx / DHL shipping items, a person residing in the remote area will have to pay an additional shipping fee.International Buyers - Please Note:Import duties, taxes, and charges are not included in the item price or shipping cost.
