The schematic of the TU-217 tuner is fundamental and very good.

The TU-317 and TU-417 are very similar and have only slight differences
to the TU-217, just 2 or 4 lamps addition with bigger mains-transformer.

The power supply was several times changed, with a different transformer and with a different stabilizer: LM7815 or similar

The 110-220 Volt version  with LM7815 ^



You may exchange the C103 of 470 µF to 2200 µF for better power-line stability.
Also C17 of 47µF to 100µF for better FM front-end performance.

The sound of this tuner is excellent.
