I'm working on a little Detrola model 247 table top job. I understand Detrola manufactured literally hundreds of different radios under their own name and others. This radio is pretty simple, 4 tubes and a ballast. The ballast is badly blackened and has big loose parts rattling around inside, so it's almost 100% likely to be faulty. I can't read the ID on the ballast, but hand written on the chassis it reads. BK55BG. The other tubes are also properly scribed on the chassis and agree with the marks I can read on the tubes so I tend to beleive the ballast really is a BK55BG. I have been unable to locate this particular Detrola model schematic from Nostalgia Air but they do have a schematic which seems to be identical it's listed as Model 208A.

I have been unable to find a replacement for the Ballast or any cross reference number. I did find some "univeral ballast" replacements at tubes and more :

Any thoughts on finding a replacement. or if I'm on the right track? And no I haven't powered up the little Detrola yet, just gathering my parts list. Thanks, hope someone can steer me in the right direction.
