I am repairing my TL922A after a grid to filament shorted tube. I found that 
one of the grid to ground rf chokes appears to be short circuited - it 
measures around 0.1 ohms. It looks darker than the coil on the other tube 
base which was actually open circuit. I managed to repair that one and it 
now measures 2.6 ohms. This is part L7 and L8. It has a Kenwood part number 
of  L33-0259-05 and is a 470uH part. This part appears to be discontinued 
and unavailable. Will this Bourns part be a suitable alternative?

I am not sure what I should be looking for.
