Have you wired the same TT to another amp and checked, alternately are all the other inputs functioning properly on this same Technics amp?

Also what cartridge are you using and what is the usage/working history associated with it?

I have encountered a similar issue, twice in the past, in one instance the cartridge was faulty and in the second, I had To change a few capacitors in the phonostage of the amp. The first instance was with a Shure M97xe cartridge and the second instance was with a NAD 304 amp

Yes have used a NAD phono preamp and connected it to my Pioneer receiver
