That said, I’ve got a nice metal enclosure on order. Help finding Replacements Posted by Dr. To compensate for 22sc3281 the raw input supply is high so that Q3 and Q4 can draw enough current through R1 and R2 to supply the pass transistor base drive and and also their own needs.

You may also like. Packaging should be the same as what is found in a retail store, unless the item is handmade or was packaged by the manufacturer in non-retail packaging, such as an unprinted box or plastic bag. This design seems good for learning though. The unit will provide two independently adjustable outputs, positive and negative of about 4V to 15V each, as well as a ground.

The “off” amount and percentage simply signifies the calculated difference between the seller-provided price for the item elsewhere and the seller’s price on eBay. Thanks so much for your time. Continuing research efforts across several industries continue to yield promising results, including graphene biosensors.


What output current will you be running and what is the linear voltage drop difference between Vin and Vout? I assume the book also explains some of the circuits?

May 7, He makes a point to really show how to wire them so they are in phase. Hopefully I’ll be ok. You’re going to be using one or two chunks of aluminum about the size of your fist.

I also picked up some mica and thermal compound. Another improvement he talks about involves this schematic, showing only the positive regulator May 6, 7. You May Also Like: Don’t forget the HUGE heatsinks and fans.

No, create an account now. May 5, 3. The gain of the pass transistors is low which is why Darlingtons are recommended as an improvement and the supply 2sc281 amp gain is also low Which is why he recommended an op amp.

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.

Wonder if I understood the first part of that design correctly as far as Vin goes. This puts you in the position of learning heat flow. May 5, 4. See details for additional description.

2SCO datasheet – Specifications: Transistor Type: NPN ; Voltage – Collector

May 7, 9. The metal chassis is not “heatsinking” when you are using W 15A power transistors! The price may be the seller’s own price elsewhere or another seller’s price. That can be used to calculate the worst case heat dissipation in the power transistors.

Feb 11, 5, 1, Repaired my German 12vdc 20amp power supply for Ham Radio.

2SC3281/2SA1302 replacements

May 6, 8. The datasheet of the transistors will tell you 2c3281 of this, like maximum temperature allowed and the heat flow resistance of the transistor.

May 5, 6. Learn about the Overlap-Add Method: Be very weary with NTE parts, they are known to be remarked devices that does not match the original parts spec what so ever.
