C179 is where the yellow arrow is pointing
you can change it to a 2.2uf 35v-50v electrolytic if you want or keep it a tantylum, but increase the voltage from 25v(stock) to 35v or 50v.

My large electrolytic cap assortment arrived yesterday. I think the ones I have in that value range are 50v so that will work out perfectly. I think I shall avoid the tantylums. Someone mentioned explosions and fire. Now I am a fan of that but not contained within my radio gear!

2.2 uf at 50 volts is what I change them to as well. Never bothered with putting tantalum ones back in. I've never really understood why they used tantalum for that cap in the first place.
Those Uniden 858 chassis were very well built at at time when there was a lot less of the cost-cutting nonsense we see nowadays... There's probably a sound reason why they used tantalum for that cap; I'm just not sure what ! Either way I've never had a problem replacing them with regular electrolytic.
I agree. I'm loving mine. It doesn't have to be a powerhouse I have the box to do that. I'm just loafing it. It's rock steady. No drift no issues. Good bones.
Modulation hard limiter. Crank up the modulation, cap explodes, radio no longer works. (No, I'm not serious, but that is the practical effect.)
Oofta! And possible side effect, radio may also burn to the ground necessitating a new radio purchase. Winning!

Thanks JJ. A poor schematic copy and out of date glasses were screwing me over. That's way easier on the eyes!
