70V PA distribution transformers.

A 70V distribution transformer with an eight-watt input tap will give you
600 ohms input.

Old 70V equipment is usually available free for the asking from your local
installed sound company.

Getting old is not recalling the alternatives offered, so I'm a dummy. I
found the filament xfmr first and tried it but it reduced volume so I
assume my radio which is non-military doesn't have 600 ohms like the
military manual I have. So I guess mine is commercial, either a
SP-200-SX or more likely a SP-210-SX and I think it has a 3.2 ohm
output transformer.
I can't find any info and I wonder if anyone knows for sure on the
commercial models output transformer's impedance.
