Yeah, but NP uses another kind of lamp!
It depends on the kind of lamp look at the Manufactum Catalog
for vintage carbon lamps! (Kohlefaden gibts dort)

Hey, i´m student. The TAD Speaker project keeps me low on moneys for some more month. A ZEN light with those lamps must look very pretty. But i would need 12 - 24 pieces for a twochannel amp. 17€ for 115W at 220V => 200 - 400 Euro for lightbulbs. I´ll try my halogen 1000W one each channel first. and i don´t need much more than some 100mW out of the amp with the TAD´s!

sorry, didn´t know that cost is an issue!

But they look gorgeous!

That is true!
If you read the Zenlite PDF carefully
you'll see Nelson Pass put in a lot of hard work/search,
before he found some lightbulbs that could
come close to give a satisfactory result in an audio amplifier.

Read the PDF once more!
