As there is a 10x ratio if I load the cart in the secondary with 470ohm, the cart will see 10sqr x 470 = 47k if I am not wrong.... do you believe it can be done ?
It will also see whatever capacitance is at the input x100 + the parasitic capacitance of the transformer. The S/N will also suffer. Still, it doesn't hurt to try.
A rough calculation gets me around 1k2 input impedance,
β taken as 200 and Ut 28 millivolts (warm transistor).
Other gentlemen agree ? Schematic again post 10938.
According to the data sheet of BC337-40 current gain may be 400
rather than 200 so Re would be 2k4 according to your simulation ..
Who can explain two simulations differ by a factor of two ?
Publish both and we will see...
In my experience the BC337-40 tends to be around 400.
Some have selected for near 500.

My guestimate was (near) 2k (no simulation involved )
