Innards of Ballast Tube L-49-B
Had a short between pins 7 & 8, so I cracked it open to take a looksee.
Resistant coil wire wrapped around a mica board. white stuff seem like plaster for glue. I suppose I could stuff it with an 180 ohm wireround 25 watt ( 3 & 8 ), 45 ohm 5 watt ( 7 & 8 ). Any tips? Tho, I did place an order for 3 NOS tubes. _JD_ |
