HAFLER DH200 DH220 DH225 TO-264 16 AMP LATERAL MOSFET UPGRADE KIT AS REQUESTED!

Description: HAFLER DH200 DH220 DH225 TO-264 16 AMP LATERAL MOSFET UPGRADE KIT AS REQUESTED!END OF AN ERA DUE TO THE DISCONTINUATION OF NOW ALL COMPLEMENTARY TO-3 LATERAL MOSFETS FOR AUDIO USE, I FOUND IT IMPERATIVE TO FIND A SOLUTION TO KEEP THESE CLASSIC AMPS MAKING MUSIC FOR ANOTHER GENERATION. AFTER MUCH RESEARCH AND TESTING, THE NEW EXICON TO-264 COMPLEMENTARY OUTPUT MOSFET UPGRADE KIT IS HERE. I WAS ALWAYS FOND OF THE ORIGINAL HITACHI MOSFETS FOR THEIR STABILITY AND SOUND BUT WAS IN FOR QUITE A SURPRISE WHEN I INSTALLED THESE NEW 16 AMP 200 VOLT 250 WATT DOUBLE DIE EXICON LATERAL MOSFETS IN A HAFLER DH-200. WOW IS ALL I CAN SAY. I DID USE TO-3 EXICON MOSFETS FOR YEARS AFTER THE HITACHI MOSFETS WERE DISCONTINUED. I FOUND THEM TO BE SLIGHTLY BETTER SONICALLY OVER THE HITACHI BUT STABILITY VARIED FROM BATCH TO BATCH . EXICON FINALLY GOT IT RIGHT. I NEVER THOUGHT THERE WOULD BE A MORE STABLE ENHANCEMENT MODE LATERAL MOSFET THEN THE HITACHI(AND I TRIED THEM ALL) BUT CAN NOW SAY THAT THERE IS A NEW KING ON THE BLOCK. THIS COMPLEMENTARY OUTPUT SET IS DESIGNED SPECIFICALLY FOR LINEAR AUDIO APPLICATIONS WITH ENHANCED OSCILLATION SUPPRESSION. NO LOADING CAP NEEDED. NO MATCHING NECESSARY WITH TWO DIES IN SAME PACKAGE.IF YOU NEED TO REPAIR YOUR HAFLER BECAUSE OF DEFECTIVE MOSFETS, OR JUST WANT TO RE-NEW OR UPGRADE YOUR 40 YEAR OLD MOSFETS , THE MUCH NEEDED MOSFET CONVERSION KIT IS HERE! THANKS FOR LOOKING!NOTE: INSTRUCTIONS AND PICTORIALS WILL BE DELIVERED VIA A USB FLASH DRIVE. THIS FORMAT INCLUDES 43 COLOR PICTURES SHOWING STEP BY STEP INSTRUCTIONS AND THE ABILITY TO ZOOM AND PRINT. THIS PACKAGE IS DESIGNED FOR INTERMEDIATE TO EXPERIENCED KIT BUILDERS.
