Home theater receivers with pre-amp outputs? - amp receivers weatherproof, but not much more

I have an old house, but very expensive theater audio system. Dolby is finally dead, but the amplifier is still valid.

There is only one receiver components (ie, without an amplifier today) on the market?

If not, there are inexpensive receiver with 5.1 preamp outputs can send my existing amp?
