Outstanding - Congrats - Now you can get to work on that output attenuator... Or you can intercept the feed into A9 and measure there (which might be non-trivial as the schematic seems a little vague on whether there is soldered hardline or connectors). Either way, great work. TonyG |

:-+ That's what my 8656B looks like after power up as well! I love seeing old HP kit up and running! In fact, I have another (incomplete) 8656B that will likely end up as a parts unit - so if you are in need of anything desperately enough to cover shipping* from Oz, let me know and I will see if I have it. * If it's only little, I could handle that. |

Thanks Tony_G, brumby! And everyone else, jeez, what a fascinating Rabbit Hole! All the input has just been invaluable! I've had a chance to re-fit the faceplate and stabilize things enough to flip it over into a proper operating posture, so I can play with it a bit. It SEEMS as if the keyboard is functional. I'm able to set and adjust frequency, amplitude, and modulation like you would expect. I'm thinking this bodes well for control overall. I've attached a couple pics of the regulator mount just prior to power up with the new 5V regulator. More to come I'm sure, JRH |

Looks nice - It cleaned up well. Just a reminder, if you can get me a model I should be able to get some of those actuators 3D printed for you. Also, those keys should be the classic Bill West design so if now you're pressing them and you find they stick then CuriousMarc did a video on cleaning them on his YT channel. TonyG |
