Oh ok will do

What would be a sub for tr12 and tr15?

you need to try an external power supply so you will know if it is the radio or power supply. if the radio works with a external supply you will know you are wasting your time changing parts and not knowing if they are good or not.

I just did that and still same result.

A little google action later

Googling 2N5484 and equivalent or cross reference yields the following results:
2N3819
2N5457
2N5486
2SK104
2SK168
2SK17
2SK37
2SK49
2SK55
BF410A/B
ECG312
FE5484

J5103
K305-18
LS3819
LS5103
LS5246
LS5484
MPF102 (MPF-102)
TIS58/

For TR12 (2SK55) N-channel FET use NTE312 or could try one from the above list.
For TR15 (2SA844) PNP use NTE234 or BC212, BC257, BC307, BC556
BSW24, 2N3494, 2SA781, KT3108A .


Disclaimer: I make no claims as to the accuracy of information presented in this post.
I just did a quick web search..

Hope this helps, also if you are confident in your parts unit (89xlr) maybe you could save time and use/pull the original parts (tr12,tr15) from the other radio! (If these parts are good/working, and you don't want to try and fix the parts unit one day..)

Which way should the 2n5484 be soldered in I can't find the way for it to go?

Match that symbol to the spot on your schematic, follow the pin-out. Gate, Source, Drain - 3,2,1

Look at the main board, do you see a half circle or square with rectangle in front of it (silk screen printed on pcb)?
