70 speaker
#1

How do you know it is a 70 speaker?
I am buying some speakers and he doesnt remember which are which.

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.

People who do not drink, do not smoke, do not eat red meat will one day feel really stupid lying there and dying from nothing.
