[ICOM] IC781 power supply

[N9QZD]

I have the Sherwood Fan on mine. Also I run it at 100 VAC. 
Heat is not a problem with this arrangement.

My  IC781's power supply is a "hot case" although  I add a extra fan . It due to its low efficiency  in  28V shunt REG powe supply . I study its schematic, I think if in receive  period, cut/close  the  28V power supply, the temp should be down greatly,But I have not think of it carefully. Any suggestion?
