@Ar9Jim Jim,
I agree with @ChrisTFM35 (son)!! We have played CD, cassette, and vinyl, with the system described above. With the 275 as the center of focus it is a very enjoyable experience. Not only does it sound great, it is also a work of art.
Got to play two new albums tonight.
One was Dexter Gordon - Go! LP (Blue Note Classic Vinyl Edition)
And the other was by an artist that @jazzman53posted above, Karen Souza – Essentials. Can't wait to play Karen Souza – Essentials II. They are both brand new 180-gram Gold pressings.
Welcome!
Posting the issues you are having as @AndrewJohn suggested is a great start. Both of those pieces of equipment are well worth the time to get them up and running.
If I may give a suggestion, look at these links as I think they will give some ideas:
Carver M-1.5t mkII, Restore and Upgrade - Carver Amplifiers - Nelion Audio
Carver C-1/C-11 Restore - Carver Preamplifiers - Nelion Audio
Carver C-1/C-11 Restore with Bill D Mod - Carver Preamplifiers - Nelion Audio
The repairs/restorations are done by @Nahash5150 He is an Administrator for this site, and I had three amps restored by him and well worth it.
Also sounds like you have other equipment. I'm sure others would like to know what it is.
Enjoy the site!
Switching over to working on a list of CD's for when I send out my TT for a restoration.
Looking at Mulligan, Desmond, Coltrane, and others that pop up in the hunt.
