Thank you, papa.
My spice simulation is showing only a watt or two of dissipation on the 1 ohm source resistor. Is this correct?
I'm looking to throw something together this weekend. Will a reduced power supply voltage at 25V DC and a 10 ohm load resistor work? Trying to work with what i have on hand.
The simulation shows the same bias current, but not much output voltage swing.

Won't this amp model like a curent source amp with a 20ohm resistor parallel with
the load. With an output impedience much like the F2?

I use those also , and they work great !
Anyway I cotacted Digikey today and I have been told that they just sell to Italy packages of the DMos for a minimum of 300 euro .... Would love to organize a group buy .
Thanks

A quick announcement:
The work for the De-Lite article is done, and I need only
to finish composing the text, which I will try to do at Sea
Ranch in a few days.
The article is being published here at DIYAudio.com 🙂
and should be up in a week or two.
Happily, the transistor and light bulb remain the same,
although I have a version with higher voltage and dissipation
for more power and still lower distortion.

Looking forward to it..... I have the Tx and bulbs, and need to order the rest of the stuff. It will be interesting to try out...

Big storm. Lucky I didn't go this week - the power is out
on the coast 🙂
The deluxe version of De-Lite needs a higher voltage
transformer. 75 VAC on secondary at is appropriate at
400 VA per channel.

I was thinking to use 110v builders transformer, you can pick 'em up cheap on the flea market,here in the UK. But what about the capacitors?160volts or so is quite lot to tackle.What if I use them for load? they nice and big and yellow.See what significant halve will say about the idea;-))
Stefane, did't Nelson say 75v ac ? Besides a cheap 220v to 110v builders transformer is likely to be an autoformer they are about 1/2 the price of a true
220v to 110V transformer. A transformer has 2 seprate windings that are electricaly
insulated. An autoformer only has one winding and a second tap at 50% . This does
make them a lot easier and cheaper to build but not safe to use in our aplication.

Report Post Reply With Quote Why not to try something else with it? Set up is so simple that is actually asking for all sorts of different arrangements.

Management at the site frowns on direct AC line applications
for safety reasons. That said, working with transformers in
the regular manner is risky also.
The De-Lux De-Lite runs as high as 100V DC for the supply,
and gets you up to 10 watts and lower distortion as compared
with the50V version.
Patience, all will be clear enough soon...
