Basicaly it is just some resistor value changes..

Default Here you can see the HRII able to 2 ohms loads


In the reality, even using 1 ohms the output transistors will survive!

Goes to 100 watts into 2 ohms...not a good advantage.

already have 75 into 4 ohms and 38 watts into 8 ohms because of rails regulators...increases quality but reduces power.

Those Sankens, i have received from Klaas Veenstra, are excelent.

regards,

Carlos

Default It ain't pretty...

but it's ready for biasing the HRII!

The build took WAY too long, but not because of any external factors, just life on this end.

Anyway, don't laugh at the plywood prototyping.

I was snow-bound for a few days and I just worked with whatever materials were available.
