[QUOTE="Family_Dog, post: 526226, member: 82"] Lekker! The Technics with which I am busy had the complete wrong transistor fitted by someone prior to it reaching me, a NPN instead of a PNP in the power regulator circuit. I could not get the correct trannie so used the closest one I had and also had to swap the leads around. Whenever I have to do this, I always use a bit of heatshrink or other insulation to ensure they legs cannot short out if for any reason someone 'wiggles' the transistor when the set is switched on. Enjoy your Pioneer, it's a fine amp! -F_D [/QUOTE]
