Hey guys,
I've been watching this forum for a few months but this is my first post.
For quite some time I have been building electronics for audio. Mainly microphones but also custom cables and repair.
Recently I got into the preamp world and my first build was a 312 clone.
Yesterday I was at a house that used to be a cinema and it had all kinds of nice equipment. I found an old box with spare parts and the guy that owns the house now gave it to me.
Some stuff that caught my attention in particular were some tubes. 2x ECC 83 and 1x EF 86. All Philips tubes, still in their yellow boxes and probably from the 1960's. Also I found a couple of input transformers, Sennheiser TM 003.
I'd really like to use those parts for something nice and I was thinking about building a pair of mic pre's, each with 1 ECC83 and an input transformer. It doesn't have to be perfect, I'd like it to sound like an old tube pre so simple is perfect.
I already found and bought this elektor article: http://www.elektor.com/magazines/2003/february/ecc83-(12ax7)-microphone-preamplifier.55031.lynkx
However I'd like your opinion. Has anyone built this schematic? And what power supply should I use?
Does anyone have better ideas? What would you do with those parts?
