TO 247 Mosfets

Besides RF, what other amp manufacturers use bigger TO 247 mosfets besides the traditional TO 220 mosfets in their amplifiers? Does anyone know?

Good question

Crunch GP3000D uses these FETs:

Case says it's TO247AC.

Are these used by Sundown and Atomic?

I'm not sure, but I've heard they use different qualities of similar components, so I'm assuming if the Crunch GP3k ($450) uses larger cased transistors, the sundown and atomic would do the same considering the higher price tag allows higher quality components.

But, don't take that for the truth, just an assumption. I remember stumbling across the SAZ3k's transistor type, but I can't find it now. Maybe Jacob or Chris or someone else who repairs amps can chime in.

What is the number and maker of the transistors?

For the RF amp? or for the crunch gp3k?

TO 247. I do not know the makers though.

Either... I am curious what they use for transistors.

RF uses 247s. You see less bigger transistors in em for a given power rating vs other amps that use 220s

I linked to the transistors used in the GP3000D-Pro.

They are made by International Rectifier, and are model number IRFP360LC or IRFP360LCPbF (latter one is Pb Free, no lead, making it RoHS compliant)

Werd got that.
