GM, for a module replacement work I acquired an "original" part, "guaranteed", from a local seller, the end result was it was indeed an "original" part but refurbished ..
So bad done also (I took apart the cover to see a monkey would have done a better soldering job) that when I installed it I got roughly a watt (25 intended).
Fortunately the seller returned the money, and I mailed (no cost) "the thing" back. But time lost ...
I guess they got this "things" in bulk, named "every spare parts for radio" combos.
If you can get the original Icom, go for it.

This is a bit off topic in some ways, in others it's something we have tossed around recently.
I have an Icom repeater that appears to have a failed PA module, it draws 10 amps and has an output of 1 watt.? It's a Mitsubishi RA55H4047M.? I have talked to Icom, they have the part in stock for about $120.? I have looked on line and I find this unit listed in many places other than Digikey, Mauser or Newark (They don't carry it).? The images of the units all look identical including 'Japan" printed on the units as compared to the unit in the repeater but all sources that I can find seem to be coming from Asia, specifically China at price points between $38 and $66.
The $64,000 question of course is do I risk one of these alleged "Genuine Mitsubishi" units or bite the bullet with Icom?
