TR-7 Bass boost For anybody interested, you can significantly improve the quality of the audio output form a TR-7 by changing a few coupling capacitors in the audio output stages. This drops the lower 3 dB point from about 260 CPS to 35 CPS.
All capacitors located on IF/detector/audio output board. You may have to hunt for physically small cap for C1159. I have a few in lab stock if you can't find one. C1159 1000uF C1153 100uF C1155 100uF C1152 0.1 uF C1150 0.47uF C1146 10uF C1170 10uF PS-7 power input relay. FOr anyopne interested, I have a modification to add a mains switching relay to the PS-7. This greatly reduces the current swtiched by the power switch that is part of the volume control/Rf gain control on the front panel of the TR-7. I have a schmatic and several pictures of the modification. __________________________________________________________________ McAfee VirusScan Online from the Netscape Network.
