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, iīm 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. Iīll try my halogen 1000W one each channel first. and i donīt need much more than some 100mW out of the amp with the TADīs!

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!

Well kept brainfunction of this old man
