MRF477 - HR2510 - Chinese options?

Buy Eleflow MRF477. It just works.
You can use MRF455, 2290 etc. Require some work, but it's worth the effort.

Also - do you know which pins those capacitors go to? There are two of them doubled up. From other HR2510 photos it looks like they attach to the final transistor solder points on the board side pictured below.

Would the fact that those came loose cause the final to smoke when power was applied to the radio? Weird chain of events.

From the soldering job on the final it doesn't look like it is the original.

If you bought new the
mrf 497 will work well from RF Parts Co. HG makes a mrf 477 that I would trust and like to find some one that sells them in the USA. I would buy some myself.
