For the KSA5 "new" power supply, pnp mpsw56 (1A) and npn mpsw061 are both obsolete.   Can I substitute it for mpsa56/mpsa06 (0.5 A)? Or can I use BD180G, which has 5V emitter - base voltage VEBO (instead of 4V in original) and gain bandwidth product ft at 3MHz (instead of 50MHz).  Or 2n4033, which has 5V and 1A (400 MHz).  Thanks in advance.
