Webcore PT4901-1 Tube Amp speaker from 1959. 1 tweeter. 1 8" Carbonneau driver model 901, 1 8" Utah electronics driver model 850. As far as I can tell it works but since the speakers are 66 years old and I don't know how to treat the surrounds to prevent cracking I'm not willing to send a signal through them. Tubes are original but at least one of them needs replacing as it produces microphonic feedback. 1/2" strip of the laminate is missing on 1 side
