Tt is a remarkable fact that a re-sistance-capacity coupled amplifier, if overlooked, mutilates the incoming signal much more obviously than does a transformer-coupled act of the same nominal capabilities. This is due to the fact that if the grid of a resist-auce-coupled valve becomes negative, a certain time must elapse before the charge which inevitably accumulates has time to leak away through the high-resistance grid-leak. In a trans-former-coupled set the grid current can leak away through the secondary, winding with comparative ease. (Continued on Page 15.)
