Foxtrot Guitar Amp - Output transformer

[cmac]

Hi

I am a newbie on the site (great site by the way).
I am returning to valves after an absence of 40 years!
I am building a 3W amp for my guitar playing son and have chosen the attached circuit from Piotr Liskiewicz.

My question is: What should the input impedance of the output transformer be. I am thinking 5K but would like that confirmed.

Regards
Chris

yes, 5k will work well.
