Hi all-
Thanks again JPM and Matt for spitballing this circuit design. I did some checking and it will be about $100 for the extra materials to build the revision as suggested in post#32. Most of this cost will be for a decent pair of 6267 tubes and some decent 0.22uf coupling caps. The rest for new electrolytics and resistors.
While this is not a huge issue, I do already have everything on hand for the original circuit. So in the spirit of educating myself, I decided to start with the original circuit and make the following adjustments.
As suggested earlier, I will byass the feedback resistor with a 0.01uf 450vdc film cap. Also, as matt suggested, I will replace the resistor on the ultralinear tap with a 21v/3watt Zener "bypassed" with a 0.01uf/350v film cap.
Please don't take this as my not trusting ya'lls advice. I don't believe for a second that Matt and JPM's circuit revisions would be anything other than amazing. But I thought I would start original and once I've listened to that for a while, I can order the new parts, make the changes, and then take another listen. After all, that's part of the fun of this hobby. I hope you guys aren't offended or you feel as if I wasted anyones time. I am very very appreciative. I'll report back. Thanks!
