1、24vdc B+ T1310 1Hy choke Output Input Ovdc B- A B C D F J* K L M M* J Neve BA-183AM card as used for line booster single-ended output Gain set GAIN: this amplifi er has an inherent gain of 11dB to pin F. The gain can be increased by taking pin K to ground (pin J) through an R and a C = the C assures

2、 gain is only increased for audio (not dc) and the R sets the AC gain R=1K2 and C=100uF will increase gain to 16dB R=110 and C=220uF will increase gain to 31dB note that at higher gains distortion will increase somewhat note that with loads below 2K ohms cap C7 may need to be increased in value to m

3、aintain low frequency response note that amplifi er should be biased with whatever load it will be driving connected. bias point for lowest distortion at operating level is not going to be exactly the same as the bias point for maximum level before clip pay attention to current while biaising - do not exceed 100mA pins E and H are not used pins M and J are shown twice but only exist as single edge card fi ngers RadioFans.CN 收音机爱 好者资料库
