That said, and obviously I’ve very new to electronics here what would be a good replacement for that pair? Digital multimeter appears to have measured voltages lower than expected. The metal chassis is not “heatsinking” when you are using W 15A power transistors! The problem is this.

Best wishes to you too, Ravi And to everyone else on the forum, too, of course. Again, please forgive my ignorance. How do you get an MCU design to market quickly?


The gain of the pass transistors is low which is why Darlingtons are recommended as an improvement and the supply differential amp gain ddatasheet also low Which is why he recommended an op amp. Here’s my attempt to describe what happens with my limited knowledge: Heat sinks, Part 2: You must log in or register to reply here. May 7, 9.

The power you need to get rid of is 45 watts at the worst. Media New media New comments Search media. Nov 9, 5, Posted by ron roberts in forum: Phasor Member Dataheet 21, That said, thanks again for your help I assume the book also explains some of the circuits?

I’m new to this. Microcontroller and possible compatible replacements.

TheOne New Member Dec 20, Meantime,If someone knows an equivalent please tell me OR give me any links. Choosing IC with EN signal 2. I also picked up some mica and thermal compound.


Hello, Have a good look at the transformers connections. I made some remarks in the schematic you posted: You can also order direct from Pioneer – prices seems inflated though http: Thanks Marry X’mas and happy new year to every one!!! Building a regulated supply as a learning exercise is a good way to understand much electronics and you hopefully end up with a useful piece of kit.

The datasheet of the transistors will tell you most of this, like maximum temperature allowed and the heat flow resistance of the transistor. Help finding Replacements Posted by Dr.
