Hi everyone,
I'm looking for suggestions for BJTs with the highest possible voltage rating that would be suitable for use as the VAS stage in an amplifier. Ideally, I need transistors with high voltage tolerance since I might use them in a PA amplifier build as well.
I’ve been a fan of the KSC3503/KSA1381, but unfortunately, they’ve gone EOL and are becoming increasingly hard to source. I’ve also looked at alternatives like the 2N6517/2N6520, but I’m not too impressed with their performance.
Does anyone know of any transistors that match or even come close to the excellent characteristics of the KSC3503/KSA1381? Any suggestions or insights would be greatly appreciated!
Thanks in advance for your help!
