Hello Tom,
Sorry to hear about your trusted power supply!
I have a Jet Stream supply I bought just last year which puts out 48 AMPS 
and has performed very well running two rigs at one time: my TS590 and the 
TMD710A.
It is light weight and noise free in the RF department.
It costs less than $150.00 from R and L Electronics.
I would give it a hard look if I were you.
Just a suggestion!
See you this afternoon on the 40 meter net I hope.
