Replace old Radio Shack MPA-46 P.A. amplifier (35 watt) (1 Viewer)

[UkuleleBill]

I have an old (discontinued) Radio Shack MPA-46 P.A. amplifier that has gone bad and I need to replace it. It had the ability to send 4-ohm, 8-ohm, 16-ohm and 70 volts.
I need some type of modern-day equivalent amp. Can anyone tell me what's out their these days. (Having a hard time finding anything)
Thanks,
Bill
