[QUOTE="JANNAS, post: 843488, member: 2211"] Jip, I'm using bd139/140 for drivers as well and Tip 35/36C at output trannies, only 100V VCEO and will be running on +-35VDC. Bought the drivers from a local shop and when I tested them the highest hfe were 112. The spares I got from RS hfe is 190, so again rubbish components around !! Then one wonders why things go BOOOM when you swith on !! >:( >:( Bloody Chinese !! [/QUOTE]
