Warp-1 Amp

[Studley]

Would be a shame not to see it come to fruition then. 100w in class A; must need some serious heatsinks !

Each channel has a box similar to this and yes, it’s a lot of heatsinking.

More technical discussions about it in the SuSyLu amp thread here

Edit Nov 2, 2021: Gerbers for the LuFo amp PCB needed for this project can be found here. A huge thank you for JPS64 for his generous time in making these layouts for the DIY community!

This is a spin-off of the LuFo amplifier discussed here, but it is sufficiently different enough that I did not want to confuse the technical detais already discussed in the other thread. Basically take two LuFo's, and connect them to a common inductively coupled choke with two primary windings, each going to ground, and wound such that the phases of the windings are opposite...

What a beast 😀

@xrk971; I’ve just acquired a used Warp 1 from the US. I assumed the manual would tell me what jumpers to change to convert the SMPS to 230/240v, but it doesn’t. Can you enlighten me please.

(BTW, this does not change my interest in buying a pair of the rev2 TPA3255 boards and HyperSET)

 

[Studley]

Found the answer to my question above; just remove jumper at J2.

 

[xrk971]

There is a jumper loop on the SMPS board. It’s very important not to plug the amp into 220vac mains with that installed. It will blow the amp up.

Thanks X.

Jumper removed, up and running. This is a very good amplifier😀. Definitely encourages me to make one with boards in PBTL / PFFB mode + HyperSET front end.
