Got another one of theese in for repair..

2 of the filter caps were vented , a 180 ohm resistor was burnt in the remote wire circuit and a 100 ohm resistor that goes to pin 8 was burnt..

Replaced all of thoose..

What would cause the new filtr caps to vent again within 5 secs??

Also i have 0.00 volts on all pins of the 494 besides pin 16 which is at 4.41 volts


Any ideas?
 
Theese are the 2 caps that vent..
