How hard it is to replace the rca input on the shindo amplifier?

Hello AG members.
I am happy to report back that I have just finished replacing the RCA input jacks BY MYSELF. It took about 30 minutes.
Thanks all of you. Now the bass distortions are all gone.
My system never sounds this good. So clean and clear. 
Thanks.

Awsome!  Did you end up buying that WES51?

Yes, I picked it up at a local electronics store near my house. I spent around $130 for the wes51, one extra iron tip, and a small can of flux. 
Thank you.

I’m glad that actually you chose the path of learning instead of hiring someone for insubstantial problem. I know many today’s audiophiles even refuse to learn to work on elementary items, but not this time indeed. The phrase on each today’s electronic component "Only for qualified technician" appeared in 90’s operation manuals instead of detailed schematics and service manuals to keep you away from learning and keep you closer to spending indeed. WES51 is very good investment for all electronic repair needs. I use one since 2002 SAME model. That tells about the undisputed quality of a tool.
Now next step you’ll be shopping for de-soldering tool I guess.

Any reccomendation on De-soldering device?
