The inside looks very much like the inside of the 113. Different layout but similar components and, it appears, also a 1 KHz motor. J. On Wed, Aug 9, 2017 at 8:22 PM paul swed wrote: > Thanks Tom I am familiar with the unit and this looks really nice. But > won't be in my

If the 115 has no motor (and I'm not questioning you, Bill) what moves the "digital" numbers? It looks like a clock drive, and the 1968 HP catalog makes reference to an "additional drum," which also sounds like a motor drive. Jeremy On Wed, Aug 9, 2017 at 7:11 PM Bill Hawkins

You don't have to use the long link. Just search eBay for item #232426132876. It's pricey because it is from one of those resellers of surplus laboratory equipment. Who was that outfit in Texas? The front picture reveals that the desiccant is saturated (indicator is pink). Rear view shows

Definitely spendy. Is the 115 as noisy as the 113 (similar but w/analog clock)? Wonder what *les douanes* would charge to get that back into USA? Could you claim an exemption because it was Made in USA? Jeremy On Wed, Aug 9, 2017 at 5:32 PM Tom Van Baak wrote: > > Boy I

Thanks everyone for the swift and comprehensive response, the specific device was purchased by a friend who is building a copy of my 100MHz OCXO PLL using an HMC1031 and he wanted to check the voltage/frequency and power specs. I had tried their Twitter and the Contact Us on the Vectron

Hi Sounds like a lot of fun getting everything to zero out :) One thing to watch for is hysteresis. The tempco may not be quite the same going hot to cold as going cold to hot. Bob > On Aug 9, 2017, at 2:34 PM, cdel...@juno.com wrote: > > HP5065A +20V supply and C-field circuit mods > > I'm

Has nothing to do with us, but there's a very clean, minty looking hp 115AR for sale on ebay with buy-it-now for ~US$1419. seems like something Time Nuts aficionados would fancy. Note, the rear silver BNCs are oxidized, and no special line/power cord.. see this item:

HP5065A +20V supply and C-field circuit mods I'm doing some more work on the 5065A and thought I'd share the results of a modification (one of several that will be done on this unit). I measured the +20V P/S temperature coefficient and got -13.5ppm per degree C. This equates well with the 1N938

Hi Actually it *is* a standard Vectron part number. Once an OEM placed an order, the specific part was issued a 4 digit “code”. That plus the base model number made up the part number from there on. On could debate endlessly if it was to make reordering easier (fewer digits to make mistakes
