List, My one big project that I'd like to complete is a SRPS for the SP 600. The total weight of the power transformer and two filter chokes is over 12 Lbs. and are quite bulky as well. The design plan calls for using a Mean-Well 110V to 12V 12.5 A power supply to feed both an up-down SRPS for the filaments and then the B+ supply.
I have a circuit from the web designed by Robert Weave and have his permission to use an expanded version that would provide the current needed for the SP 600 B+. The B+ supply will need shielding and a torroid filter output plus additional filtering to tame the unwanted RF. That will my problem after building it. I can buy all the parts but my problem is making a PC board. I attempted in the past to use the free ones available on line but it was a total failure for me. What I need is for someone to take the parts I supply and lay out a PC board which I'll have made in China. I would include all the documentation that I have so far which include a single SR stage and pictures of it. I really, really, really need someone who could do this right away and not be a "winter project". If you can help me do this please contact me off line TIA Perrier ______________________________________________________________ R-390 mailing list Home: http://mailman.qth.net/mailman/listinfo/r-390 Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[email protected] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html
