Could some electronics guru please help ? What is the minimum base current for the 2N3055 ? The On Semi data sheet that I downloaded is not very helpful. Thanks in advance for your help.

Could some electronics guru here please clarify the following. I did a SPICE simulation of a coil driver. A simple astable multivibrator @ 150 KHz provides the signals @ the bases of two 2N3055 BJTs. The collectors of each 2N3055 is tied to a coil. The coil is bifilar, with the common node connected to a 15 V DC source. Each inductor of the coil has value of 0.075 uH. The emitter of ea...

Since my dual 2N3055 driven flyback power supply was accidentally thrown away, I was pondering building another until coming across subject mentioned assemblies. They're on eBay and elsewhere. Looks like various drivers with flybacks. Example: https://tinyurl.com/y4lzxt85 Questions would be: 1) Do these have built in diodes? I DO want to be able to drive a HV multiplier. 2) Perfor...

I tried building a single transistor LED flasher like this : http://cappels.org/dproj/simplest_LED_flasher/Simplest_LED_Flasher_Circuit.html I didn't have the recommended 2n2222 - I tried with a BC548, 2n2369 and 2n3055 - None of them work. I'm using a trimpot set to 2 kiloohms and a 470 microfarad capacitor. Instead of a 100 ohm resistor I put 3 superbright LEDs in series. I get 1.2 v...
