Where can I hear classic horns in southern california?

Would love to hear an Altec A5 or similar. Where can I go to hear some classic horn setups?




I started an FB group 13 years ago The horn loudspeaker forum consider joining mine or others. Have 16000 members in the group many in Cal.

@johnk  I would love to but no way I’m using fecesbook. 🤮 Any way to join without it? Is there an email list?
