| | tone control on your d104-m
have you ever wished you could change the tone on your d104 like you can with the 575, I did and its easy,
the late d104 and the 575 use same amplifier and same cartridge but the 104 uses a fixed load resister and the 575 uses a 100k in series with a 2meg potentiometer, if you want lots of bass then clipping the load resister will do the trick but i dont recommend that even though some have done it and are happy with the sound, a better way is to use a 2meg potentiometer in series with the 270k fixed resister thats in the mic already, unsolder the end of the 270k thats connected to ground and either insert a 2meg/2.5meg pot, middle wiper leg goes to the lifted 270k resister and one of the remaining legs goes to ground this will give you a good range of tone adjustment, or if you want to be stingy you could just use a fixed resister around 500k to 1 meg to get a bass boost without going ott, heres a pic to help you locate the resister
if you just want to remove some trebble for ssb
use then a small value cap in series with a 500k resister connected from the wire end of the 270k load to ground will do it, I would start with a .0022uf cap and see how it sounds if its removed too much then go smaller on the cap.
tom bearden taught me that quantum entanglement allows thought to travell faster than the speed of light, this explains why at first you can think somebody is smart but if you wait a while you will see they are not very bright at all.
