Transformer 1:50, input 1.2V nickel-chromium battery, output 5V, add load, the output will be reduced to 2V, the load capacity of the circuit is so bad?

This circuit may be able to debug enough efficiency, but there is no way for mass production.
If it is a mass product, it is recommended to give up this idea to save the cost to make this circuit. Use a suitable boost DCDC chip to realize this power supply honestly.
If you are just for fun, you can try: adjust the transformation ratio, adjust R6, change 4148 to 5819, replace other types of RCC circuits, replace 8050 with MOSFET, and reduce the impractical.

It is best to use a suitable boost DCDC chip to achieve this power supply. Check on TI. There is always one suitable for you, with only 5 or 6 external components, simple and reliable.

The tube power is too small, and the battery has a poor load capacity.
