Hi All, I have a problem with my SX-727. Currently, no sound from the phono or am/fm tuner. Aux works fine, as well as the tape monitor. For a little backstory, I've been hacking away at this thing for a few years now. (thanks to the helpful info in this forum). I've replaced the majority of the Caps, as well as replaced bulbs, cleaned with De-Oxit and replaced some transistors. Everything has always worked, somewhere along the way, however, I lost my Phono and Tuner output. (I primarily listen to the Aux). The tuning and signal meters seem to be working, just no sound. The last change I made was replacing the whole head amp board. (long story short, I fried some of the tracings trying to get at the transistors.). I attached my new board via wire splicing the 10 connectors (probably not the most professional method), but I did check for continuity and all seemed good. Any ideas for some simple things I can check to help get the phono back?
