Chuck, if you ever start back up in the rewinding business I’d like to send you the transformer from my 565 that needs some help. Please keep me in mind. I’d pay more than $100 for it as well.

Congratulations to you and your wife as well as your son on achieving his PHD! You have done a stirling job in creating an environment to nurture his intrinsic motivation. Well done. Oh, BTW - your

Hi, My transformer winding machine lurks quietly to my left as I sit at my computer workstation composing this post.... I think it is time that I re-explain my transformer project, and provide a

John Hunt: See the TekWiki for specs and manuals on all 3 versions. The BW depends on r probe used and not the variations _/A/B. The noise is a bit worse on AM503 than A/B. BW about same on all 3 for

Jon, I'm curious why you have found that the AM503B is much improved compared to the AM503.??The manuals show noise spec of the AM503B (with the P6302) being slightly better (<250uA RMS)? vs.

Mike exactly, but AM503B is much improved over 503. We use both P6302 and the giant P6303 gun for high current Very useful for SMPS, low PRF current pulses. But P6302 is very easy to break, and

AM503 and a P6302 probe? Mike

we use the DC HALL effect to 50 MHz tek probe and matching amp for LF DC work. The small clamp on are never accurate at LF even with 134 amp j

I needed the low-frequency extension you get with the 134's active transresistance termination. ________________________________ Sent: Thursday, February 8, 2024 7:52 AM To: [email protected]

Oops, ok I now understood that you where referring to was the LF COMP adjustment, as there is only one for all probe types, and not the gain adjustment. Agree given the switch selector for the probe

WOW, Chuck great to see you jump in, agree with my notes? how are you doing? All fine here, jammed with planning and business for 2024 Have an absolutely fantastic day! Jon

I am certain he meant time scale. -Chuck Harris <Manxduke@...> wrote:
