Fighting the Dunning-Kruger effect.
My TU-666 tuner came today. It was an Ebay purchase. I initially thought I had overpaid, but the condition is even better than advertised. Clean inside and out. A few dings on the faceplate, and just a scuff or two on the wooden cabinet. Everything works except the stereo light, and I'm hoping it's just a bulb. Selector switch is a little scratchy.
It sounds good into my AU-555a, AM and FM stations are about where they should be on the dial, sensitivity seems better than my Kenwood tuner, and the green dial is just gorgeous. No way I'm going to put in LEDs.
Solder joints and boards look fine, no heat damage that I can see, none of the original electrolytics is swollen or leaking.
I'm tempted to just re-do the power supply, replace the four 2SC458s, and leave it at that. Leave all the other caps alone. I haven't found any threads talking about any other known failure-prone components.
But, I like to tinker.
What would you do?
