TA-N88
TA-N88B
(november 1977 - 1984)

Class D ! Huge power in small boxes, at last !
Long awaited and shown here and there throughout 1976, this amp had it all: PWM (Pulse Width Modulation), PLPS (Pulse Locked Power Supply, 20kHz chopping rate) and 4 pairs of complementary V-FET !
Perhaps a little bold for many of the TA-N88s still around are... dead - the slim-line box probably was too slim to hold all of these slick circuits. The underlying technology inside the N88, however, showed the path we now use daily - d i g i t a l !

TA-N88 = silver ; TA-N88B = grey ; Japan only saw the original silver version and a truly black version is supposed to have existed. Companion of the TA-E88B worldwide bestseller.

Do read the ZN technical review to understand why so many TA-N88s fried all too quickly - a fate which had nothing to do with the V-FETs.
