However, if the tube is driven hard enough for grid current to flow (CW operation), the 15 ohm resistor introduces additional grid bias and the tube operates as a non-linear class C amplifier. With the built-in supply shown, it can be operated at an imput of about 70 watts, or up to 90 watts with a 750-volt supply. With its ability to deliver clean and clear sound reproduction, the 6146B tube is often employed in professional audio equipment, including hi-fi systems and audio mixing consoles. 29Mc F3ï¼6146ãƒªãƒ‹ã‚¢ã‚¢ãƒ³ãƒ—ã®æ‰‹ç›´ã—ã¨1å¹´ã¶ã‚Šã®QSO 2016å¹´ 05月 28æ—¥ 今週ã¯ã€é€±æ—¥ã«é€£ç¶šã—ã¦å¼·ã„EスãƒãŒå‡ºã¦ã„ãŸã®ã§ã€ä»Šæ—¥ã¯æœã‹ã‚‰Eスãƒã«æœŸå¾…ãŒè†¨ 6146B 8298A The "little firecracker" linear amplifier Linearity and output It should be recalled that the figures given for audio service in Class A, AB1, AB2 or B can be used for r. 5 to 30 Mc. 1989å¹´ã“ã‚ã«ä½œã£ãŸ50MHz 6146Bã®ãƒªãƒ‹ã‚¢ã‚¢ãƒ³ãƒ—ã§ã™ã€‚ 「6146B リニアアンプã€ã§æ¤œç´¢ã—ã¦ã„ãŸã ãæ–¹ãŒå¤šã„よã†ãªã®ã§ã€å›žè·¯å›³ 6146 (ãŠã‚ˆã³åŒ A/B) ã¯ã€æ›¾ã¦ã¯ã‚¢ãƒžãƒãƒ¥ã‚¢ç„¡ç·šã«ã¦å¤§å¤‰ãƒãƒ”ュラーã ã£ãŸ UY 807 後続ã®é€ä¿¡æ©Ÿçµ‚段用ã¨ã—ã¦ã‚‚ã€æ¥å‹™ç”¨ã®é€ä¿¡æ©Ÿã«ã‚‚広ã使ã‚れã€ä¸€éƒ¨ã§ã¯ AB2 ç´šã® pp アンプãªã©ã«ä½¿ã‚ 6146パラリニアã®ã†ã¡ã€é›»æºå›žè·¯ã¨é€å—切り替ãˆå›žè·¯ã‚’除ã„ãŸéƒ¨åˆ†ã®å›žè·¯å›³ã‚’æã„ã¦ã¿ãŸã€‚ 定数ã«è¨˜æ†¶ã—ã¦ã„ãªã„部分もã‚り〠The amplifier consists of two 6146B Beam Power Tubes in parallel providing ~100W power output on 160 - 30 Meters and slightly <144MHz 2B94 リニアアンプ> ストリップラインã®çœŸç©ºç®¡ãƒªãƒ‹ã‚¢ã‚¢ãƒ³ãƒ—ã¨ã„ã†ã€ã‚ã¤ã‚‚ã®ã«æ‡²ã‚ŠãŸç§ã¯ã€ä¸€è»¢ã€ã‚ªãƒ¼ã‚½ãƒ‰ãƒƒã‚¯ã‚¹ãª2m用アンプをã“ã—らãˆã¾ã—ãŸã€‚ ã¾ãŸã€ã‚ã®ãƒ„ノãŒ2本 807/EL519 真空管ã¸ã®ç›´æŽ¥ã‚¢ãƒƒãƒ—グレードã¨ã—ã¦ã€ã“ã®è»ç”¨ 6146B ã¯ã€ãƒ´ã‚£ãƒ³ãƒ†ãƒ¼ã‚¸ KWM 2 トランシーãƒãƒ¼ã¨ç¾ä»£ã®ã‚µã‚¦ãƒ³ãƒ‰ アンプ プãƒã‚¸ã‚§ã‚¯ãƒˆã®ä¸¡æ–¹ã«å‘ã‘ã¦ã€å†· As the 1950s progressed and SSB began to replace AM as the preferred mode for phone operation, the tube proved ideal in linear amplifier åŠç”°ä»˜ã‘よりã¯ã‚‹ã‹ã«ç¢ºå®Ÿã§æŽ¥è§¦æŠµæŠ—ãŒä½Žã„ã®ã§ã€24V200Wリニアアンプã»ã¨ã‚“ã©ã«ä½¿ã£ãŸã€‚ 真空管アンプã§ã¯ åŠç”°ä»˜ã‘よりã¯ã‚‹ã‹ã«ç¢ºå®Ÿã§æŽ¥è§¦æŠµæŠ—ãŒä½Žã„ã®ã§ã€24V200Wリニアアンプã»ã¨ã‚“ã©ã«ä½¿ã£ãŸã€‚ 真空管アンプã§ã¯ã€20A30Aã¨ã‹ã¯æµã‚Œãªã„ã®ã§ã€æŽ¥è§¦æŠµæŠ—値を 音ã¯å‰ã®FETã®ã‚¢ãƒ³ãƒ— (2SK408/409パラプッシュ50WOUTï¼‰ã«æ¯”較ã—ã¦ã‚りã¯ã‚ŠãŒã‚ã‚‹ã¨ã„ã†ãƒ¬ãƒãƒ¼ãƒˆã‚’ã„ãŸã ã„ã¦ã„ã¾ã™ã€‚ ãªã«ãŒé•ã†ã®ã‹ã‚ã‹ã‚Šã¾ã›ã‚“。 6-HIGH-FREQUENCY TRANSMITTERS A Single 6146 Amplifier The photographs of Figs. . 6-64, 6-67, and 6-68, show views of an amplifier using a single 6146.
