That can be used to calculate the worst case heat dissipation in the power transistors. It’s for a power supply May 5, 3. Don’t forget the HUGE heatsinks and fans. It’s a character flaw, or the fact that I’m where the town where the phrase “New York Second” originated You must log in or register to reply here.

Phasor Member Dec 21, Replacing a 4 pin leaded inductor with a 2 pin Started by gkmaia Yesterday at I assume the book also explains some of the circuits? Well, the deed is done.

The emphasis on safety in the book is quite big, so I imagine that “heatsinking” Q1 and Q2 to the chassis shouldn’t be unsafe. Meantime,If someone knows an equivalent please tell me OR give me any links. Especially that transistor chapter. I’m new to this.

The unit will provide two independently adjustable outputs, positive and negative of about 4V to 15V each, as well as a ground. He does mention that it’s a basic design Later in the book he talks about replacing Q3 and Q4 with Darlington pairs as one possible improvement.

I made some remarks in the schematic you posted: There is a chapter later in the book with some mods to allow for better voltage regulation By continuing to use this site, you are consenting to our use of cookies. Another improvement he talks about involves this schematic, showing only the positive regulator Not good on price, but simple to use.

Nov 9, 5, If you post a schematic diagram that will help a lot. In the end, the question of whether using the chassis for heat dissipation is wise or not may be overshadowed by my obvious ignorance and the fact that I’m sure that there are better designs for a power supply.


Resistance to heat flow is called, “theta” datasheeet this resistance is always defined as between two places. Be very weary with NTE parts, they are known to be remarked devices that does not match the original parts spec what so ever. Your name or email address: Quote of the day.

You might have some good luck with the MJE series parts.
