Hello from Australia Prakash I have exactly this problem with my yaesu and wonder can you help with part numbers of the modern components you used for the repair :) thank you sir

Dear Matt, Good day,
Pls Try 2 actions:
1) Replace all Existing Tantalum Capacitors on PA Unit with any brand Electrolytic Capacitors 10mfd 35V or above. And try Power On Rig, if did not work, you need to check Relay coil & power supply circuit for Power On Relay operation.
2) For Power On Relay function circuit the components you need to check and replace are a) Q10 Transistor 2SD892R or any simple NPN transistor can work. b) D10 & D12 Diodes Si 1S1555 or use any high speed Diodes 1N 4148
The second action may not be require for many cases. Download FT757GX Service Manuel from web.
Good luck & feel free for any other info on [e-mail] 73 de VU2KPU Prakash.
