ﾄﾅﾄﾄﾄﾄﾄﾄﾄﾄﾅﾄ so I made a note

It uses a standard E ferrite transformer core ﾚﾄﾄﾄﾄﾄﾄﾄﾄﾄﾄﾄﾄﾄﾄｿ
except there are two bobbins one on each end ﾚﾁﾄﾄﾄﾂﾄｿ ﾚﾄﾂﾄﾄﾄﾁｿ
rather the one in the middle. This magnetically ｳInv ｳ ｳ ｳ ｳZap ｳ

it can be shorted out or not without affecting ﾀﾂﾄﾄﾄﾁﾄﾙ ﾀﾄﾁﾄﾄﾄﾂﾙ
the UV lamp inverter much. ﾀﾄﾄﾄﾄﾄﾄﾄﾄﾄﾄﾄﾄﾄﾄﾙ
If the UV tube gives up, try a double sided PCB with 2 rows of blue LEDs
mounted instead of the lamp and across 12V...

And to reduce the inverter power, add a 10n across Collector to Emitter and
change the 1K5 to 12K for 75mA @ 12V total load.

Why don't U send an interesting bul?
