Re: HP 6114A - looking for R8A, 15.82K 0.1% 1ppm resistor
Note that you can land close enough with some reasonable like 1% 50 ppm common resistors, at least to get it running and make sure that's the only problem before investing in a fancy resistor. You

They'll also be happy to make it 15.82K, as they're laser-trimming the part to exact value. [email protected]> wrote:

Ed, TCC makes bulk foil (for Vishay) in count one (literally) for about $20-40. For instance, a Z201 which is 0.2ppm TC at 0.1% runs $23.29 plus shipping. Radu. [email protected]> wrote:

Re: HP 6114A - looking for R8A, 15.82K 0.1% 1ppm resistor
Those kind of resistors are custom values and high performance, so a direct replacement will probably need a junked donor unit. You can buy a new custom one but it might cost a couple hundred bucks

Re: 8920B Receiver Synth "Out of Lock"
Yes. Calling Rick on Monday. I'm confused by the part numbers. I was in fact misreading mine: it's 08291 -61020. Even with that, HP Parts has no match for that. (?) I also looked up 08920-68127 (from
