Looks like your little amp is indeed at line level and would require pre-amping for, say, a magnetic pick-up cartridge.
This is clearly a fun object with no hi-fi pretensions. Lighting up the valves with blue LEDs would tend to give the game away, rather...
Perhaps I've missed something along the way (not unusual). Assuming it isn't just for headphone use, how are the loudspeakers coupled? Is it capacitive, or if not, where are the transformers? And how much power output could one reasonably expect from such valves, driven as they seem to be by very modest HT?
