Looking for replacement amp recommendations for recordette

[TheCuriousDevices]

Hi, I’m having trouble with my recordette output changing as it is running or producing sound through speaker instead of head if at all. The electronics looks like a birds nest of free floating vintage and modern components and i would really just like to bypass the whole mess and run the Shure head directly from an amplifier without blowing it up. Any recommendations or advice for this? Preferably something that can run from 60hz 240v. Thanks
