Differences between the old AGI 511 and the 511A?


Hi, I'm from Italy and I can't find the differences between the AGI 511 and the 511A. Is there someone who can help me? Thanks, alessandro

Not that you're probably interested any longer, but I believe the main difference to be the use of discreet transistors in the phono and line stage of the AGI 511A in place of the op-amps used in the phono and line stage of the original 511.
