Sankyo 名人会GPA Parasol Man replacement speaker

[onslow]

Hello,

I have a Sankyo 名人会GPA Parasol Man in a 'Stellar 2000' frame. Everything on it works great but it was missing the speaker.

I found a replacement speaker at a surplus shop that works but I'm certain the wattage is too low and unsure of the correct impedance. I'd like to know what the correct speaker for this machine is. I don't want to damage the amp. I assume it's 6 Ohm.

Could someone with a similar machine take a look at their speaker and give me the specs? Maybe someone has a parts machine and would sell me the speaker?

I know this came in two different frames but the speakers should be the same. The pics show the different frames.

Both pics found on the web.
