Estate sale Fuselier speakers for $370 but I know nothing about them.

Well if the OP has already purchased all 4 of the speakers he might select a pair that needs little work. Then money may have been well spent.

I was asking about the volume controls on back of the Rotel amplifier. 

Given that the volume issue is the same via the phono input and the tuner and it also seems that the gain from the Eskinsin is not much higher, only providing 3dB more gain when used direct into amplifier, I suspect that the amplifier is defective, possibly in the input stage. What is output voltage on the Eskinsin?

Glad to hear that the speakers worked out. What sources are you using?  

By sources I meant vinyl or digital as music sources . I thought the Rotel 951 was a CD player. The Kenwood KR3130 is a receiver from early 70s. 

If  interested in upgrading the electronics you might start another thread requesting options for a integrated amplifier that would serve your sources, speakers, room size, and budget.

No apology needed. Now I believe I have your situation figured.

You use a TT and a streamer into your Kenwood, taking advantage of the phonostage and line level preamp while bypassing the internal amplifier. The Kenwood is connected via the variable output (pre out) to the Rotel amp. 

The Rotel amp has volume for matching to different preamps. Do you have the volume full out?  I am trying to figure why you are only getting 65dB output.
