If the BG psu is the one Rob referred to, it has some flaws..... The max ac input is 24 AC, rectified will give around 36 v at the reservoir cap.....this is right on the edge for the TLO op amps used in the design..... |

that is it John the one Rob has, can't do pics as my internet is soooo slow, but will try tomorrow some time late when the kids are in bed and the net not so busy,, tis a little diddy cap. It uses three that look the same but have the number range 101, 103 and 104, as said will try a pic tomorrow. Thanks. Lyn. |

Clacking bell! I was minding my own business, measuring DIY spotwelder controller with a transformer and doublecheccked each time all is fine....Then it got time to measure thyristor and ofcourse I checcked that scope body was "zero" and same "zero" that line that feeds the thyristors. I put the shuko on :zap: Yup this outlet could go either way...I though I did not fiddle with it. Wife noticed that fuse blew, because outlet from that bedroom went off too. I was affraid that that I fried the scope, but noooooo.....Just good oldfachioned scope "ground" to phase error :doh: :doh: :doh: OK. This scope is nowwhere as good as these beauties, but maybe it's easier to float. Pretty german Phillips (Two tubes, othervice transistors) does not sync. I got one nearly as old UK made one and that mostrly works... Where you get 1:1 and 1:10 scope probes? Pekka |

Lyn. --- End quote --- Hi John I think Lyn is referring to the 0 - 30 v PSU http://www.banggood.com/0-30V-2mA-3A-Adjustable-DC-Regulated-Power-Supply-DIY-Kit-p-958308.html , info attached . My 0 - 30 v psu kit arrived yesterday along with the frequency meter kit :zap: Rob |
