bxi1206

This amp has the sfp50n06 in the power supply. I can't find them anywhere I would want to order from except from ebay.

Mouser has listed an alternative STP45NF06

STP45NF06 STMicroelectronics MOSFET

dont trust them. irf 3205 will work.

Does 47ohm gate resistors sound right for this amp? They are all discoloured. Half read 69 to 73 ohms and others read 46 47ohms

timwebb · 2012-05-21 2:38 pm

They are 47ohm

In photos of a BXI1206D that I have, there are 22 ohm resistors so there may be 2 versions of this amp. It's unlikely that you'd have so many that were near 47 ohms if they were supposed to be 22 ohms.

Maxxsonics refered me to CIA Engineering. The gentleman on the phone had infomation about the bxi1205 that used the sfp50n06 with 22 ohm resistors.

ive seen sfp50n06 with 22 ohm resistors in similar amps.i think it should be fine both ways.

I was a little upset that maxxsonics couldn't answer this simple question. They said its proprietary information.

timwebb · 2012-05-22 4:04 am

i know right. its not like they fix them.

spooney · 2012-06-08 12:52 am

Hell you would be lucky if anyone at maxxsonics on this side of the ocean actually knows that info.

I completely forget I have a 1206 sitting here.. DFP50n06 & 22 ohm gate resistors in it. I was going to use 3205's when I put it back together though.

Does anyone know the value of r122? To me it looks like 1k, but its dis colored and rusting. Also r107?

blazer40 · 2012-06-10 4:46 am

here..

DREW028 · 2012-06-10 5:43 am

I was wayyy off. Thanks for the pics.

DREW028 · 2012-06-11 9:02 pm

I think yours might be a different rev than mine. The layout doesn't look the same.

Perry Babin · 2012-06-12 3:19 am

Post a photo of the resistors and the area around the resistors in your amp. They may have used the same layout in a similar amp.

This is from a 1606. The red bands sometimes look a bit brown on the dark blue resistors so you'll have to use your judgment on the colors.

Question what kind of fest are in the out put side

timwebb · 2012-06-16 6:44 am

640n's
