Here's some food for thought. The original Pre-amp project occurred as a response to Colin's request for a cheap but decent Pre to use with his new Sex Amp. Douglas Sector 7g or (T to us) came up with a nice useable and cheap option. We tied his hands with the caveat that it needed to be cheaply built. And he did a great design job. However the parts required for the PS have little use beyond this particular circuit iteration. Personally I have a foreplay already; what I would like is to use his amp section with a much highher quality power supply using excellent iron and fully tube rectified. This may be a similar connundrum for others. So until either Douglas returns or one of us can do the design work on the new PS it is on hold. See I don't want to have to buy parts twice for the same pre. But by purchasing the good stuff now I can use it again if need be to make changes as they appear. The difference of 100$ for a high quality transformer over the cost of the suggested one is minimal if you can use it again and again.
