Hi. I repair this vinatge Nad, who was with short Left channel.
I replace with new original 2n3055/2mj2955, R453 (180om was open), Q411 (2SD669A-short), Q413(2SB649A).
After replacing short part, i connect 100 watts lamp and turn on amp. The lamp is not light /there is no short in amp/, check right channel -0V, left - 8v, 9v and up to 13 V. Please tell me, where i was wrong?
