this project clearly show the purpose of 103 tripot and use of 2n222a . hope this will help you finding your question.

A great project. Has it had any new updates?

The unit of power is not amps. you should use Watt. as far as I understand you question, you want a 100 watt supply with volts vary from 1 to 220 volts. The output power we can calculate by using formula P=VI so you can vary current and volt to get desire output power. To vary current and Voltage you can use transformer. cuphead

Are there any reputable transformer brands you can recommend to me?

for whoever reads this can be useful,took me a while to figure out

The EGS002  Will ONLY produce waves for more than 3 seconds IF...

1»»»»»  pin 1 (over current)  must see LESS than 0.5 volts DC  (2  blinks of the egs002 led  if not...); 

 15»»»»»  pin  15  (output voltage feedback signal) MUST see between  2.75 to 3.15 Volts DC;   set the little blue pot. to  3.0 Volts to test(3  blinks if over 3.15   OR 4 blinks if under 2.75 V) basket random

  16»»»»  pin  16 (over temp) must see  LESS than 4.3 volts (5 blinks if over 4.3 vdc)

These are the ICs FACTORY values ,and I  confirmed them myself on my own inverter builds

Not ONE youtube channel teaches these things,is it on purpose? i should start my own...

Many thanks, It's useful for me.
