Roger that AndrewT, at first it was the A Channel working fine, and the B channel mute. I did what Andrew suggested.

I just inverted the cables and sure enough, The B Channel was working fine and the A channel was down. Meaning, the AMP is fine. It's the PREAMP.

How much more does this forum permute? I got a good camera and I can expand quite a bit. Problem is if the net and/or the forum will permit it. Unless you send me your Email and I'll send them direct. BTW, I'll delete it after you send it.

I've sent for two sets of 1/4 inch to RCA cables to see if the RCA outlets are still good. The input of the AMP are 1/4 inch and the Gemini also has two RCA outputs.

If not, I'll be looking for a home PreAMP that has a phone outlet for my turntable.

The connection faults are not likely the cables almc, because you can swap them to prove they are good or not in seconds.
The problem you have to deal with is most likely INSIDE the preamp. and the INTERNAL wiring and connections. This is not a simple, user maintenance matter of plugging things in and out of sockets.

You will require phono inputs for turntables and they must have impedance correctly matched to the type of cartridge fitted to the player arm.

OK, guys, I'm back. This time I just waited for a set of 1/4 to RCA wires. I plugged them in the Crest AMP from the RCA jacks and now it works in Stereo, sort of. Which means, as you can see in the above picture. The 1/4 wires plugs outlet were waisted. But the Gemini also has a set of RCA jacks that can be used as outlets also to work with the 1/4 CREST V900 AMP plugs. Done

This time, when I use both channels. It sounds like crap, It sounds better with the balance to one side or the other. Let me explain.

I place the balance in the middle. Both channels sound...horrible. High sounds and voice, but no bass!

Then I turn the Balance nob toward the left side, or the right side completely. Then it sounds great, like it should sound. With bass, voices, and music.

What's next?

If your speakers are wired out of phase that's the sound you will hear, no bass and all phasey.

Make sure + and - connected the same on the amp and speakers, that's in phase. If you have one channel reversed + on amp to - on speaker that channel will be out of phase with the other channel, no bass and weird sounding. But normal when only one speaker is playing.
