Default B718, D758 equivalents

At 1.25W, they seem not to rate above many of the obsolete TV CRT driver transistors like BF469/70, 2SC3503/A1381
or Fairchild KSC3503/A1381, still commonly used as VAS transistors. However, these are TO126 package rather than TO202.
If they will fit, and I believe they are reversed pin order, you have several more choices there too.

Default But you have a wonderfull ancient history... wonderfull place you are

Sakis.... troubles you have will be past in a matter of years.... ask Germans your money back because of war.

In 1988 we had 5 percent inflation in a single day...was crazy...we had to receive payment and run to buy food or the price gonna increase 5 percent in the next day....if friday payday, then we would loose 10 to 15 percent.....and you see how we are now days...we became rich in a matter of 20 years.

I hope you are fine dear Sakis...hugs to Maria and to your son.

I am not that fat anymore Sakis.... i win the battle against weigth and feeling myself as Ulisses (warrior).... daugther that is Menelau in his family name (yeah, from Greece) is wearing a shirt that is already giant to me...oversized now a days to me..... watch the lady.... isn't she gorgeous Sakis?..... yeah...i do think she is...and clever Sakis...high scores in the school, speaks english fluently..will be a Medical Doctor and very soon.

Her name is Larissa... 177 centimeters tall lady...her name is a place in Greece too.

regards,

Carlos

well done uncle Charly .... always very nice to hear from you ...

I am happy for you and family ...here in Athens the good thing is that after all we still manage .... Luxury is out of the question but other than that we do fine

warm regards and all the best for your health ( even though it seems that you destroyed the wonderful look of the... big ....fat ...uncle Charly we used to know ha ha ha )
