I am striking a deal to purchase a lot of Mosfets. there will be around 6-9 extra K135 (2Sk135) Toshiba NOS Mosfets available @ $7.00 each if anyone has a use for some.
Or if you have some extra J50 (2SJ50) Toshiba Mosfets for trade. please let me know.
These are the TO-3 case Fets that are used in Soundcraftsmen amplifiers and one up from the K134/J49 used in the Halfer 200/220 amps and im sure many other amps used these.

Hi,
Soundcraft and Hafler used these MOS? They must be really
good!
I used them in Slone's mirror-image designs but now
the replacement is plastic to3p case, k1058/j162.
I don't understand why the manufacturer stopped
making them.

Hi Zerol Cool,
I have some extra Hitachi 2SK135 & 2J50, which is not used? Do you still need them now?

hi zero cool. i have a soundcraftsmen pm860 with a bad 2sj50. would you know where i can get a replacement?
You realize you have replied to an 18 year old thread?
Anyway these days you can source Exicon ECF10N20 or ECF10P20's which are current production TO3 lateral MOSFETs
https://www.profusionplc.com/type/lateral-mosfet
To quote from the blurb: "The ECF10P20 is a suitable equivalent or replacement for the 2SJ50 or 2SJ56."
You might find a single original 2SJ50 but be aware there are counterfeits about from unreputable sources.

thanks, do you know what the bias procedure adjustment is on the pm860? any help would be appreciated
Glad this popped up - I recently blew the R channel on my pmf2150b and 3 of the mosfets were dead 2xn 1xp. Nice to be able to get replacements! Have ordered. If anyone has any functioning 2JS50s and 2KS135's send me a pm I will purchase.
Success! She lives to fight another decade, or until I short the outputs again, probably. But good to know these MOSFETs can be found. I thought she was scrap metal for a bit there.
