[ICOM] Internal PS question

[Steve]

Are the built in supplies really of the switching type especially in 
the older 735?
I've always assumed they were just good old linear type supplies with 
no noise problems. I guess I never really looked to see if there is 
room inside for the large transformer of a linear type supply.
