I had the same problem today the hardest part is getting in to the pa side once in it is 2 screws on each 
and 4 solder tags on each took about 20 mins to get the blf147`s out but about same if not more to strip 
the radio down.

I have emailed about 6 places for price and availability and so far  www.adsemi.com is the only one to 
reply {its late I know}
Stating I would need to buy 5 Pieces at $50 each

I hope someone somewhere will do only 2 so will wait for others reply before I send for them

How did the pa`s burnout on yours?
