I picked up a 100 watt matching transformer at a radio show for 2.00
today. The primary is 4 ohms and the secondary is rated "70 volts 100
watts". Has anyone ever used one of these so that a conventional
amplifier could be used on a 70 V line? Could anyone think of any
problems that could be associated with doing this? Thanks, Lenny


It will work OK, if it's a good transformer. It will convert a 4
ohm output to 50 ohms. 5000/100 = 50

We did this back in the '70s when 'smart' AKA 'cheapskate' customers
bought the wrong equipment, then they wanted the system fixed.
