--- Quote from: Vgkid on December 07, 2016, 10:24:02 pm ---Nice job on the power supply. Is that a HP5335 besides it. What is the large black box? --- End quote --- I may add a preset voltage switch to the power supply. I often use 3.3V and 5V. Quicker than twirling knobs. Yes, A HP5335A to the left. The black box is a wavetek 178 waveform synthesizer. Finished repairs and calibration on it a week or so ago. Now I need to find a place for it. Here is a post with some pics of it: https://www.eevblog.com/forum/testgear/repairing-a-free-wavetek-178-waveform-synthesizer/msg1068993/#msg1068993 I should see if there is a thread on here for "Show us your favorite huge heavy boat anchor instrument". The power supply is nearly as heavy as the wavetek. Linear power supplies are quiet (low noise). I'm very noisy (Groaning & grunting) when I need to lift it :) |

Here's my Homebrew PoS made from a PC power supply: Edit: Argh picture trouble Had some brain fade originally and had to move the ground terminal. I do intend to build a better one at some point which has fully adjustable current & voltage with a purty digital display. |

Transformers alone will probably get you close to the price of a chinese power supply. --- End quote --- Or better yet, a quality used PSU from eBay. ;D Granted, this is far more of a challenge outside of the US, but it's not impossible based on what I've seen. |

I never liked that 'black for ground, red for everything else' on that era of HP supplies. On the supply I had to repair I just replaced all three with some good pomona binding posts, in red, black, and green. |
