[ICOM] Internal PS question

[Paul Manuel]

The 735 had no room for an internal supply. The others were switchers.

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.
