[-] Re: [ICOM] IC-775DSP power supply

[Paul Playford]

Thanks for the response Joel.

I have a schematic and a partial parts list of the psu and have already 
replaced 3 parts.

It appears my problem is with the ic on SUB1, which is an M511977FP pulse 
width modulator voltage regulator.

I thought others may be interested in my findings as I go along.
