What are the problems with the 440-T and 220-T MPX boards?
There is not a whole lot to go wrong with these circuits, so it should be easier to repair them than to design and build a replacement with an IC PLL demodulator. Then there is also the issue of maintaining originality....
Glad the output transistors finally showed up. Now you can get back to the power amp repair while waiting for the remaining parts.
