Philco 91 Speaker Replacement
#39

95 is roughly the square root 9000.

OK, so you have 5.3 Ohm.

Look at 4 Ohms as the closest.

Let's solve this:

the closest in 4 Ohms column is 8,800, when connected to 3 and 5.
Now, 5.3:4 is 1.325.
So your 8,800 become 8,800 x 1.325 = 11,660.

This is pretty close to 10K you need.

However, you could also use 4 and 6. This will give you 6,400 x 1.325 = 8,480.

Also, you need to add to these numbers this to your 680 Ohms of primary DC resistance, more or less (I am not getting into reactances and complex impedances)m which will give you 9,160 Ohms, which is also pretty close.

So, use either 4&6, or 3&5, either one is good enough, 4&6 being closer.

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.
