Detrola 247 faulty Ballast, help me replace it
#1

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.

IF can wire size and Rubber mounts?
Renovated Radios do carry what you need. As for the voltage, a wire should be at least 300V-rated.morzh — 11:13 PM
