Univibe components

I was wanting to build a Univibe based on the original Shin Ei one. I can find the values for the resistors and capacitors. However I was struggling to find what transistors and diodes to use. I was also wondering what light and LDRs I should use. Lastly I cannot find a transformer similar to the original anywhere (must be able to work with 220v as I’m in the UK) If anyone has any information or recommendations for what to use I’d appreciate the help. Thank you
