Title: [OZ] Silicon Chip - "Valve Sound Simulator"
Post by: ic on August 18, 2014, 09:22:13 AM

Heads up for any Aussie forumites, the August edition of Silicon Chip magazine has an article on a solid state valve simulator.

I don't understand the nuances of the circuit, but the input goes into an LM833 with variable gain which then feeds into source follower JFET (2N5485). There is then a loudspeaker simulation circuit which uses a TL074 (apparently they have an LTSpice file on their website.)

Cheers,

Ian.

You can find the first two pages (33/34) online: http://www.siliconchip.com.au/Issue/2014/August/Nirvana+Valve+Sound+Simulator (takes some time to load).

JFET for distortion and TL074 for frequency response. Two channels (stereo).
