Pass "DeLite" Amp from BAF - Page 3

Tea-Bag · 21st October 2009, 03:35 AM

The lightbulbs represent a 20ohm load. I think that a reasonably sized Power resistor would work here, but this amp has nothin to do with this thread. If Nelson would give it a pet name for now, such as School Boy amp, then we could get started, or maybe Depletion mode Mosfet amp. Guess that wood work.

Time for me to read the review of the real J2...

How about "Atouk"? - A good name for a Caveman says Ringo.

We will find them at flea markets aside tubes in the future.

What a crap! Let's all get eyes disturb with those horrible energy-saving fluorescent lamp

What about instead of using a light bulb using a few tubes instead just using the
heaters for the load resistor. Kind of a passive hybrid.

Well, for the Diy'ers in countries with the green light bulb problem, you can also use water heater elements.

In the US I tried a few and I think I scrounged up some 4500W units that are about right. 4500W/220VAC 10ohms(they were actually slightly lower) but you have to watch out for the temp they get to in the open air. They come in several shapes and sizes.
There is a version of Zen Light on this forum somewhere built exactly that way. You don't get any of the warm glow though

There are still alternatives, for example this 105W halogen light bulb. Take a look here:

HalogenglÃ¼hlampe klar

I think, they are beautiful!

Manufactum says, that their phase out date is september 2016.

The water heater element idea is brilliant too! Think of an amp with included coffee/grog/glogg warmer!

OK, liquids and electricity do not go together well...
