Default memphis 4k amp repair

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

I have 3 semiconductors on the sidewall that look the same but have different part numbers. Can i use just the same on all of these.

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.
