[R-390] NOS Hammond 600 Ohm to 9 Ohm Audio Transformers

[robert.boyd at servicecanada.gc.ca]

More blatant commercialism.........I have several NOS Hammond 119DA transformers, 600 ohms in, 4 and 8 ohms out @ 12 watts. Same price as Andy's

Hi

They are a lot better thing to use than the "single tap" transformers  
you see running around. Matching impedances isn't a bit deal with  
solid state gear, but it does matter on something like an R390
