The Wolverine 5th Group buy

[hcpower]

So far the updated spec-sheet only shows enhanced rail voltages beyond ±71VDC for the EF3-5. Is there any chance this will do for an EF3-4 V5 if components are selected correctly?

Best regards

No

Cudos to all involved what a fantastic product I can't wait to build a fully symmetrical version. I may need Perspex lids to show it all off.

Thanks again to all involved these take so much energy and time

Well done
Steve

Trying to read up on the Wolverine project. Hope I'm not too late to get in on the group buy.

What would be the ideal transformer voltage to power a single EF3-5 Wolverine?
Is there a schematic for the power supply?

Please take a look at the first post of the build thread.

The build guide will contain alot more guidance on power supply layout including schematics

Thanks Stuart, sorry I didn't see it.

High chance of being fakes with many of the MT200's. Unless maybe buy from a brick and mortar store in Japan that can show you some parts tracing.
FWIW Those transistors aren't on the BOM list for the amp. (Thats not to say they wont work, they just aren't tested or proven)

The biggest, baddest output that is still readily available is the MJL4281/4302 combo.

Looking at the data sheets, the MJL21193/4 appears to have double the 100v SOA of the MJL4281/4302 pair.

They are slower however and not as linear with increasing current drain.

Overall a more durable output stage though?

You are right, but I was referring to just the wolverine. MJL21193/4 is not suitable at 4mhz, all wolverine outputs ~30mhz
