This may be a good candidate for freeze mist. Start with the signal PCB
around the jungle IC. Spray small areas & if you get a reaction put
some freeze on a Q-tip & touch individual parts. I would almost guarantee its
one of those little electrolytics.
Be a shame to junk it. Its got a strong jug & one of Zeniths last good sets.
You can put pixs on it & maybe a bouquet. You cant do that with a LED set !
