These 169's had alot of Vertical problems. First I must assume you have Source B+ voltage so here we go. Replace C-503=2200uf@35v,U501 (8-Pin IC), C-518, CR-503, C-520=33uf@50v,R-513/220 ohm SMD (Service Mounted Device) runs from the negative side of C-520 up, CR-503, CR-502, C-518, and C-521. These are the worst case problems.GOOD LUCK::David:: |
