Hi Pix Just did a bit of research. Try the 74HC73. No one lists a max and min output current but the absolute maximum ratings are given as +/- 25mA. (sink and source) which gives you a chance of a few mA to drive your transistor. You might even go lower than 3k3Ω to make sure of switch on. If you have source trouble Jaycar stock these.

Reading the datasheet on the 74LS74 I have 20ma which I’m hoping is enough.
I already have these so I’m keen to use them up.
If they don’t work I’ll source some 74HC73s
