So I did a full electrolytic replacement, replaced diodes d2,d3,d23 with 1n4148. Replaced D24 with an NTE109. I have NTE 109 and NTE110 and wasn't sure of the best replacement.
Anyway moving along I checked the ceramic disk capacitors in the above section and found the smaller 104 was bad or not a 104. I cant tell if its a 104 or a 3 with a line under it so I replaced it with a 104 as the cap had no other markings. Then I put that aforementioned mod area back to the original configuration.

Radio sounds great!! Furthermore I was feeling adventurous so I added the md-1 and cp-1 boards to the radio. Upon opening the amp section I found the two flyback resistors across the top very dark. They test 15 ohms I assume they are 10 ohm 5 watts but this expected in a 40 year old radio. I will have to order these and replace them but for now its working.

TX and RX are both great and just some small adjustments to the ALC, am power and modulation and I think its a wrap. I have plenty of diode stock and might just replace the glass diodes due to age but need to look more into where to use a NTE109 or. NTE 110

Also it looks like a have a brown wire on the back of the face that I cant seem to find where it goes.

I hope this information can be useful for anyone with similar problems in the future.
