Many moons ago you may recall that I was messing with the idea of a high gain low watt amp using those old car radio tubes with the 12V plates & heaters. Time is easing up a bit around the house so I'm slowly ressurecting the project. Now to the point...
Some earlier threads had mentioned using 70V transformers for ceiling mount paging speakers as output transformers. First of all, will this really work? Second, I'm having trouble finding any with a primary impedance listed. They're all spec'd at wattage. How can I find this out?
cheers,
