But most or our boombox gang capacitors all got a cover over it and it is only exposed in tube radios where they have air gang variable capacitor.
He said to REMOVE the plastic cover. Frankly I think this is all bad advice. It is nowhere near a reliable repair method and can be equally destructive as it is helpful. Most Boomboxes use cheap varicaps that have plastic fins which are easily distorted. Might I add any distortion or damage to the fins ruins that varicap and by extension, the Boombox tuner since you’re not gonna find a replacement? Also removing the slugs from those coils…. Yeah, same deal. It’s bad enough as a general advice but novices with no tuner experience can quickly ruin an otherwise repairable Boombox. Lastly I will say this… if Hopey can produce a stereo signal generator, a sweep signal generator, a frequency counter and an oscilloscope, and demonstrate proficiency in operating them, and if he has an understanding of superheterodyne principles, I’ll give him the benefit of the doubt and eat my words, but until then, I’ll stand by my position that these are just plain bad and potentially dangerous (to the Boombox) suggestions. It’s true that if there’s milk finding it’s way inside a varicap, it can certainly alter its capacitance, but the average and most common tuner failures aren’t milk in the tuner or the slugs, they are other issues. If you buy a Boombox for $20 and you don’t care if you trash it in the process of tinkering with it, go ahead. But if you care about your Boombox or it has some value… don’t do hack ****.
