Man, time sure does fly. This is the first time in weeks I've had a chance to sit down and write a serious post. I've started looking around for parts and trying to combine this pre with other projects.
I did, however, get the Bottlhead SEX amp (BTW it is integrated and does not a pre) built. The voltage check was dead-on, but the smoke test was just that - SMOKIN' SEX. I toasted the PS transformer. Pulled it apart and found I missed one solder joint. I'm hoping that was the only problem. I should have a new transformer in 3-4 weeks.
I pulled out an old project that I set aside a couple of years ago. It's a chip headphone amp I saw on headwize. I'm should have this up and running in a day or two.
Back to the present. I have been playing around with PSU Designer (Duncan Amp Tools) for the power section. Pretty cool interactive tool for designing both tube and SS rectified PS - and it's FREE. I am still really leaning towards John's original idea. It's simple and there is a very done web site. Did anyone catch the Power Point presentation? One of the pictures is hot-linked.
John, you mentioned beefing up the PS. Haveyoulooked into upgrading the parts? You know, beeswax caps? Seriously, the part count is so low that it might be a worthwhile project for each of us to do a slightly different variation of the same theme just to see how the sounfd is affected. I would have no problem sending mine to you for a head to head. Maybe you could do an honest write-up, like you mentioned over at the Dungeon. I am still trying to resond to that post. I've got a few stories to tell about honest peer review......Colin
