How do you know it is a 70 speaker?

They need re-coning though. Do you want one Fredrick if it needs re-coning?

Sure Kirk, the 70 speaker will have 3 wires coming off transformer to plug it instead of 4. Four wires are for the 90 with push pull other than that I think they are the same. Also I do have enough speaker grill cloth that you asked about, the gold color chain link pattern. PM me

Doesn't the 20 also have the 3 wires... How do I tell it from the 20?
Message me the total for the grill cloth if you are sure you want to sell it.

Well
Nut is not the tell-tell; some of 90 speakers look same as 70 but electrically are like 20 for pushpull version and like 70 in SE.
The 4 wires mean pushpull (20 and some 90s), 3 mean SE, 70 and some other 90s.
