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
