That reminds me, should anyone have a schematic for an SR 830 walking amplifier, can you please get in touch with me. I have one that keeps eating voltage regulators. > On Nov 12, 2017, at 12:12, Dr. David Kirkby (Kirkby Microwave Ltd) > wrote: > >> On 10

Re: [time-nuts] Favorite counters (current production)?

Hi Don’t get me wrong here, I think the SR620 is a great counter. My concern is that the design came out a *long* time ago in terms of solid state generations. If things work out as they often do, some random part in there is going to go obsolete. What part and when, I have no idea. HP has

Hi, I would say CNT-99/91 and SR-620. Bob has a point about 53230, since the others is older, but on the other hand, it is a bit of a gamble. There are many aspects that goes into the longlivety of a product, such as access to components, but also strategy of companies. The CNT-90/91 an

[time-nuts] Favorite counters (current production)?

What current production freq counters do people like for general time-nuttery these days? There's a chance I can get a decent counter for work, so I'm looking for suggestions. Bonus points for fanless. Don't need anything past 200 MHz or so. Prefer ethernet over USB or GPIB. The SR620 looks
