Well, my bulk buy of BC549C's has arrived, so one more question before I get started on the amplifier...
How closely do I need to match the transistor pairs? Can I just go by HFE reading on my cheap digital multimeter, or for best results do I need to break out something a bit more serious? If so, what exactly? :)
Can I just use my 8405A and check that there's exactly 180 deg phase and equal amplitude on each side?
Thanks,
