A-143

2008-11-20 by Andrew Nitz

I have a hammond A-143 that I just took the reverb unit out of. it was wired to the far right 2 of the 4 connectors on the right side of the preamp, and there was a tube adapter thing that it was also wired to. the tube right under the tone control knob. I took out the reverb unit (it was not stock, it's a reverb mate reverb) and I took out the stock reverb amp. there were only 4 wires connected to it when I got it. 2 of them went up to a box by the vibrato scanner and the other 2 went to the speaker. I cut those off and now my organ sound is really weak.

Ive seen in some pictures of A-100 series organs that there are 2 wires coming down from the right side of the preamp down to the power amp. Mine doesnt have those wires there. I was wondering if maybe they were taken off when the replacement reverb was put in...


How can I fix this??
I tried to wire the reverb units back in, but it didnt change anything
