Here’s a pic of my boards. I think I have 6 pairs left

I am building a couple of integrated amps for my kids. My plan is to use the Hypex SMPS400A400 which will put out about 62V normally on 115VAC. I will run these at 36dB gain. I am using 2SB1560/2SD2390 outputs with .39 emitter resistors. I am listing the input section transistors to find out if there is something better to use.
For Q1, Q2, Q4 I plan to use BC546
For Q7 I plan to use BC556
For Q3, Q5 I plan to use TTC004B
For Q6 I plan to use TTA004B

Does anyone have better recommendations for readily available transistors for the input section?
