Nice one, for thos who have a 2k5W psu handy. 😀
I wonder how you do 280Vpp from a +-100VDC supply?

This is a TK2050 and Meanwell PS I put together when they first came out.
Back then I thought it sounded pretty good but now days it doesn't compare to the less expensive TPA 3116.
I called it my tripath under glass 🙂

You tested it 1250 W @ 8ohm on the video, but stated 2500 W @ 4 ohms.
BTW: where is the amp? 🙂
Yes, Because the same test was conducted at 4OHMs also, I didn't make a video for that.
I am planning to conduct another test at +-120VDC soon, Hope to post some info soon.
hi sir i have a few pcs of irfs4227 around . ,can a single pair work comfortably in ucd +/-95vlts 2ohms , 250khz
Here's my first dual chip ( stock ) paired with a Pyramid regulated power supply. Some of the dual chip boards have two heat sinks while others have one long one. Makes no difference.
Thanks pg, how do they differ from the single chip yj board? Are they just higher output and have the extra input? Might have to try one.

They're advertised as 2X100 vs 2X50 for the single chip but that's a stretch.
With the same PSU the dual chip seems more powerful but that may be just my perception.
