Question Need a replacement transformer

I am looking for a power supply transformer for a bass amplifier. It needs a 120 volt 7 amp primary with two center tapped secondaries. One center tapped secondary for +60 volts and -60 volts ranted at 100 watts into a 8 ohm load. And the second one centered tapped for +85 and -85 volts rated at 300 watts into a 4 ohm load. I need only one transformer. What would my cost be. Please indicate shipping cost also. I live in Michigan at a 48383 zip code. No hurry on the delivery, and the least expensive ground delivery transport available is fine. Thanks,
Dave

Let's make more datailing.

We need calculated the power:
1)Two outputs 60-0-60 (100W), the curent os 100/120V(60+60)=0,83 A
2) Two outputs 85-0-85 300W/170 = 1,76 A
3) Total Power 100W+300W = 400W
4) 400W/120V = 3.3 A

What kind of amplifear do you built.
For bass-combo (music) or for hi-fi, high-end amp?

A ask you for what kind of inductance we may calculate.
For low class many forms put 0,8 Tesla
For high-class and speed and attack curent rate and minimilise distortion which will go to a signal way I put 0,4-0,5 Tesla?

What your looking?
