the field coil was open circuit on the speaker  it should read about 2500 ohms 

 

i removed the bobbin and found the wiring was all rotten  refitted new cotton covered cable and wrapped 

 

the coil is the choke for the power supply and it makes the magnet for the speaker

 

this bobbin slide onto a round shaft witch then has a 2nd coil that sit in front  this coil is called the hum bucker coil its wired in series with the output transformer its job is  to canal out hum etc

the field coil speaker was open circuit it is a really sexy magnavox 6 inch speaker in really good nick

 

now this kind of speaker may not be familiar to most people may be some old timers hahahahahahah

 

the field coil has 2 jobs to do 1st acting as a filter choker on the EHT for the power supply 2nd making a magnetic field around the centre pole witch is inside the voice coil basically  an electric magnet short version

 

bought 2 new bits of wood veneer  for the 2 side pieces on the top water damaged 

 

next i will need 000 steel wool 4 litres of turps spray gun and gently give him a good wash

That's all G[r]eek to me, but it is a beautiful looking piece and it should look awesome when restored.

^_^

Have you done any more resto jobs like this?

I'm guessing you have.

If so, are there any pics of previous projects?

:)
