Hi, im trying to fix my 4k amp and 18 total transistors part numbers H031 75345G AV9 and H014 75345G B2S are blown. Where can i find these or what is compatible with these. Are these H014 75345G B2S compatible with NTE159 transistors.
Thankyou |

HUF75345 these are Fairchild semiconductor parts. Mouser, digikey should have them.
sent from an IRFZ48N

The P, G, S suffix indicates the case style. Look at the following datasheet and order the ones that match the transistors that you have.

Should be a 100 ohm but will check again when I get home and can post a pic of the backside of the amp, where the inductor is at.

I just replace that resistor with 100 ohm and repair the inductor on a 16-mdc4kw just need a quick view to insure that l8a is good to go.
