new to forum amp repair help

[rebelbull]

hi glad to be apart of this forum i hope someone can help
I got a pal buddy mobile 250 amp and i got a problem and dont know what to do
i was talking on it driving in town and i hit my whip antenna on a tree limb and my amp started making a loud rumbling sound and quit working didnt recieve anything i turned the amp off and could hear as usual
i dont know what do do or waht i need to test and how to test it i hope it is a easy fix as i dont have a job at the moment and im hoping i can do the repair on my own. cant be that hard there isnt that many parts in it
i have attached a picture of the amp to show whats in it maybe someone can point out on what and how to test thanks very much

was the receive preamp on at the time?
were you keyed up when it died or were you receiving?
where did you hear the "rumbling" noise from? from the amp itself or from your radio's speaker?
what is your SWR with the amp inline and off?

will the amp key up? (do you hear the relay in the amp click when you key the mic?)

the more details you can provide, the more help you will get.

right now i am wondering about the receive preamp transistor(s).
