Replacement ARP 2600 speakers?

[Grant Richter]

Hi All,

I just got an ARP 2600 in for repair.
It looks like one of the internal speakers
is open circuit. Is there a source for these
anywhere? 40 ohm speaker.

Also, this is a very early unit with the original monophonic
keyboard. It has gold "Different Fur Recording Studio"
metal plates all over it. Anybody remember this unit
or "Different Fur" recording studios?

Thank you,

Grant
