i have about 40 pairs of these transistors .... come in as a replacement parts for ALTAIR pro amplifiers
any ideas of a schematic that can be used in ??
i am not looking for something especially powerfull ...2transistors per board and 50watts will be just perfect
thanks sakis

Perhaps this types are the electrical (not mechanical) successors for the good known TO-3 types
2SK133-2SK134-2SK135
and 2SJ48-2SJ49-2SJ50
for compare and more information I have found this:

i have about 40 pairs of these transistors
J352/K2221 = 2SJ56/2SK176 in plastic dress code. (also Plastic J351/K2220 = 2SJ55/2SK175 TO3s )
Whenever i read J55/J56/K175/K176 i can't help but think Tandberg.
The 1S number of Lateral MOSFETs doesn't exactly advertise the use of single pair output stages.
Not in the mood for Speedy Otala inspired stuff ? => http://sportsbil.com/tandberg/tia-3012-sm.pdf
jacco,
sakis,
where did you get them?
Not at all, the J352/K2221 is in fact better and more closely matched.J352/K2221 = 2SJ56/2SK176 in plastic dress code. (also Plastic J351/K2220 = 2SJ55/2SK175 TO3s )
sakis,
where did you get them?
i got them as replacement sets ( matched ) and they where supposed to be replacement parts for Altair pro amps but these amps except a few electrolytics in the protection circuit and secondary psu normaly never fail ...
so now that i dont have to keep the transitors (the time limmit expired )i may as well use them for something else

The 2SK2221 – 2SJ352 lateral mosfet pairs are 200V 8 amp devices.
They could be used in almost any circuit for the lower voltage lateral mosfet output pairs such as the 2SK1058 / 2SJ 162.
Typically they would have been used in multiple sets to take advantage of the higher voltage rating.
For instance
2 pairs could provide 150W / 8R, & 250W / 4R at +60V / 0 / -60V
4 pairs could provide 300w / 8R, & 500w /4R at +80V / 0 / -80V.
8 pairs could produce 500W / 8R, & 800W / 4R at +100V / 0 / -100V.

Please I need two j352 and two k2221 all that me costaria that was sending to paraguay. my mail is fran-doliveira@hotmail.con .gracias from already
