alright just got around to ordered some z44n (bunch of them) and some resistors. however, im missing a diode or thermal sensor, as someone mentioned.
i NEED to know the part # to this and maybe a link to where this can be purchase or any other substitution device.
my amp

2150: this pic is from ampgut and it has the TS1 in place.
2200: this pic s from ampgut and it has teh TS1 at the bottom right.

An externally hosted image should be here but it was not working when we last tested it.

It's only a temperature sensor(ie:thermistor) whenever the HS gets too hot, the thermistor shorts and turns off the PWM. If you live in Phoenix, like me, then it may be needed. It should not be too big of a deal if it is not there. As long as the amp has plenty of ventilation the HS should never get that hot. If you like you can find a comparable part. Find the PWM number and find out what it needs to disable the chip. I guess 60 to 65 C would be a good trip point.

50k NTC Thermistor
Don't know if this is an exact replacement. I had to replace one in a 2300. Smashed it during reassembly. Measured ~50k at room temperature, so I replaced it with that part.
Interesting how the 2150 uses diodes for bias comp. The 2300 uses thermistors.
