Hi all, I have an Admiral TV that I always wanted to fix, tyhe original problkem was only with the Vertical Pot. who was broken but it was lost for about 15 years. There is lot of number attached to teh TV but I have not luck to find any info related to my TV. These are some numbers that refers to the TV:

Under tehh PCB: AD-T; F459-T
On the chasis: 15D4238-1
There is a diagram that points : 40A505-340(D)
Also, on teh back pannel of the TV there is this number that say "For servicing and Parts use the next number: 43D706-1E.
