EXICON ECF10N20 AND ECF10P20 LATERAL MOSFETS. TO-3 PACKAGE. THESE MOSFETS ARE RATED FOR 8 AMPS 200 VOLTS. I USE THESE TO REPLACE DISCONTINUED HITACHI 2SK134/2SJ49 2SK135/2SJ50 2SK176/2SJ56 MOSFETS.YOU WILL RECEIVE 1 N CHANNEL AND 1 P CHANNEL DEVICE . ALSO A GOOD REPLACEMENT FOR SEMELAB BUZ900 BUZ901 AND BUZ905 BUZ906. NOTE FOR HAFLER AND MARSHALL FANS: THIS IS THE LAST OF MY STOCK AND THE LAST CHANCE TO PURCHASE TO-3 LATERAL MOSFETS AS THEY ARE ALL OFFICIALLY DISCONTINUED NOW. AS AS ALWAYS, THANKS FOR LOOKING.
IF YOU HAVE ANY CONCERNS ABOUT USING THESE MOSFETS, PLEASE FEEL FREE TO DROP ME AN E-MAIL. I WORKED IN THE AUDIO INDUSTRY FOR BOTH DYNACO AS A TECHNICAN AND HAFLER AS A PROJECT ENGINEER FROM 1974 TIL HAFLER WAS SOLD TO ROCKFORD AND AM QUITE FAMILIAR WITH LATERAL MOSFET DESIGNS.

FEEBACK LIST:
Ed - got both amps done, they sound great. Do you have a recommended bias current for the Exicons?
Ed - well, after some time accumulating the exact parts I needed, I've completely rebuilt one of two monoblocks. I put one on the bench and ran it into an 8 ohm load. So far, everything is working flawlessly - I haven't detected any oscillations, instabilities, etc. Things measure cleanly on the scope - Residual noise seems low on the scope.
Installed the transistors you sent me into my XL280.
Output looks very good. I think performance on a square wave might be slightly better than original fets. If they weren't so expensive, I'd buy more :)
thx
Ed
Received module safe and sound. All back together and working great,
low DC offset. Thank you very much for the fast turn around Ed.
Hello Ed: I just fitted your capacitor upgrade kit on the DH-200, Wow what
an incredible difference, one channel had even different components than the
other, your kit really did the job. I also fitted the Exicon set to the
other channel.
Thanks again for your parts and help, super happy the Hafler sounds superb.
Ed: Oh boy, I just did one side and will be testing it out shortly, the bias set up just fine.
I have just now put through payment for another set to complete the other channel.
Can you confirm if the same Exicon MosFet can be used on the P-225 Hafler, I have just received this P-225 Amp and have not even opened it up.
Ed,
I recieved the mosfets today and installed them. I was nervous about the outcome based on the previous owners experience when he changed them out. Regardless, it seems to be working flawlessly.
Feel free to add my experience to your list. I, too, am glad there is an up-to-date replacement.
