| Do you have any test equipment in your lab that uses vacuum tubes? |

HP 410C Electronic Voltmeter HP MODEL 11036A AC PROBE (I'm not shouting, that's how it is listed in the 410C manual) Leader LSG-11 RF Signal Generator. BWD 511 Oscilloscope (non- functional at present) All the other stuff is solid state.(actually my dipmeter used to be a "grid dipper", using a tube, but I modified it to use a FET) |

--- Quote from: BravoV on September 09, 2019, 09:30:51 am ---The only one in the house, Heathkit vacuum tube voltmeter, a freebie meter. --- End quote --- Actually those are pretty decent meters. I had forgotten about them but I still have a couple of them around here somewhere. One of them still has a NIB 25,000 volt probe with it that's never been used. I think I paid $2 for it and the meter about 10 years ago. Around that time the ham fests were full of these meters and you almost couldn't give them away. Other than the Heathkit meters yes, now that I think about it, I still have a lot of tube type stuff. |

I have some tube stuff that gets used here and there - Sprague TO-4 and -5, a Tek 575 mod C curve tracer, HP 200CD audio generator, HP 428B clamp-on miliammeter... Most of the other tube stuff is more for collecting's sake, though it's fun to occasionally use the old HP counters and see all the glowing heaters. -Pat |

Its so easy to use, and verry precise. It only needed a new cap for the internal reference a few years back. The downside is the 32mA output, almost 32mA more than 1 need. The output is in series with a relay that should eventually kick in above the 32mA. Colleague got a shock from the his 3kV version once (415B), he was not amused. --- End quote --- Did you mean a Fluke 412B? the HP 41x Series are all meters not HV supplies. David --- End quote --- You are right, but it does match my HP gear quite well :-+ I have 3 CRT scopes and a Philips nixie tube voltmeter if they count, but I don't really use the voltmeter. |

I have and still use on occasion an old Tek 453 with tube HV rectifiers and nuvistors in the H and V sections. I've had that scope for over 20 years and never had a problem with it. |
