[Marsupial]

Thanks MrFixr55.

The vm-1200a has a ceramic cartridge.
It is mono, to match the 47-1230 that is also mono - it is partly why I chose that phono.

The signal it outputs is too quiet for the radio preamp stage (that has no settings as you said) but the sound is clear.
It's just too low.
Like... About half the volume of the radios.
I need to crank the radio volume to max to get something suitable to listen.

At some point I had made a preamp with a amp-on-a-chip - and it worked, even remained somewhat clear unless I cranked it very high - but I dislike using microchips to increase the signal into a tube preamp. Feels wrong.

I am thinking a suitable step-up transformer could do the trick without adding transistor era to the signal.
