So by doing the repair by yourself, you saved almost $500
So $300 for a good donor radio - which you bought, was as much as what it was worth!
Kudo's for fixing it yourself.

ps. - ICOM builds junk, and instead of fixing their mistakes, being a man and saying I goofed and recalling a number of units, they do a really neat thing, they turn their back on their customers, change the model number , rectify the faulty part in the new model and keep selling it to anyone willing to buy it.

That is the only thing that holds me back from buying anything with the ICOM badge on it.

I agree on the pertinent monetary facts as stated especially with regards to shipping to said repair facilities, yes a bundle was saved on a rig with the glorious fish finder.

So back in the day Icom decided to actually listen to a qst review, even replacing or modifying the rig qst tested and sent it back to qst, receiving a better review afterwards.
Then Icom produced the -A version of, you guessed it, the 751. And it was a fine rig.
Then they came out with the 761.
Then the 765 an upgraded 761 a year or so later.
Then the 746.
Then the 746 Pro.
Then came the 756, more or less a hybrid 751 with dsp and a fish finder.
Then the 756 Pro.
Then the 756 Pro 2 with audio fixes developed by HAMs for the Pro.
Then the 756 Pro 3, and that ended the line.... oh wait, ever looked at a 7600?
My guess is the 7600 is the latest version of the 756 Pro series.
Yazoo has followed Icom to a degree by making -A models of problematic rigs such as the 991 original flavor, now called the 991A.

On Project 756 Pro, looking into the appropriate diodes to replace the noise blanker pad, speccing parts is fun! Pretty sure the ones to start out with are gonna be schottkys as they are fast switching and low capacitance, but if they don't result in an improvement will go pin types. With before and after noise examples to follow.

They have to be bigger than the noise floor, but you knew that.
