![My Dad's Vintage Hi-Fi Fisher Amplifier KX-100 / KX60 Tuner 1883389-0](https://www.eevblog.com/forum/index.php?action=dlattach;topic=394174.0;attach=1883392;image)
I had saved my dad's old Hi-Fi. Sure it has sat around ever since. Noticed my wife had decided to move the box to the garage, which is just one step closer to the dumpster. So I brought it back into my lab where it is safe for now. The amplifier is a Fisher KX-100.
I remember going with my dad to buy it. I've spent countless hours listening to it. Like my wife's grandmothers old radio that her mom remembers listening to as a child, I just didn't have the heart to let it go to the dump.
The amplifier has not been powered for several decades, so first things first, check to see if it has any damage. First thing I noticed was one of the finals appears to have started to leak. I remember being around 11 or so YR and one of the tubes failed. I had my mom take me to the local store (tubes were common then and they even had testers for customers to use). It turns out, this is the tube that appears to be failing. Note the others are still marked with Fisher.
Opening the chassis up (zero concern about any sort of shock, as 30 years of sitting, everything should have discharged. lol). Started going through all the caps and sure enough, one was shorted. Outside of that, none of the smaller caps appear bad.
I then started to reform all the electrolytics. Nothing appears to have a high leakage. I'll let her sit and cook.
The case is made from cheap plywood. Similar to how I have made cases for some of my home projects. The wood had split where the grill slides in and it had a couple of deep scratches I wanted to smooth out. After repairs, mixed up some stain to match the original colors. I have no plans to use poly on it like I have with some of my projects. Thinking just some oil and I'll call it good.
Maybe tomorrow I can turn on the chassis, less tubes, assuming all the caps check out after reforming.
