Re: Some interesting Nuvistor information
I just think Nuvistors are cool. Any information on how they were made is interesting to me.
I've heard they were made in a high vacuum chamber with the assembly machinery in the vacuum chamber.

Re: Building an HV Multiplier for 455/465M
Barry,
You are correct, they are not the same as the 465/465B. The 455/465M was endowed with a unique HV Module that includes a 1 1/2x multiplier plus DC restorer and other circuitry inside that

Re: Some interesting Nuvistor information
One of the NuVistors used in Tektronix scopes is designed for very low anode voltage, about 30 volts. I have a 423 I got at a hamfest that uses them. One was so weak it was impossible to get the trace

Re: Building an HV Multiplier for 455/465M
The 455/465M use a 3X multiplier but there is no HV output level listed on the schematic or in the circuit description section ( odd)
The 465 Uses a different multiplier but no listing of the

Re: Building an HV Multiplier for 455/465M
Is it the same for a 465M as for a 465/465B? I'm thinking they're different but not sure.
Thanks,
Barry - N4BUQ

Re: What is this plastic dingus called?
Thanks, guess I should look at the mechanical diagrams more closely.
Can't find this part anywhere, it's not preventing the pot from working, it's just a little annoying.

Re: DSA 602 "partial enhanced accuracy" at each startup
Hi,
And David DiGiacomo's DSA602A with FW 2.23 does it also!! Maybe it is SN (thus Board PN) dependent? By the way I can live with it. After 20 minutes you also must start the EA procedure for

I found that knowing the part number 352-0100-00 and "holder" didn't help when searching for a replacement. In some instruments the trimpots are mounted on a "stand-off" but that search term also gave

Re: What is this plastic dingus called?
Well, the original question at eevblog says it's form a 1S2, so look at the Mechanical Parts List and Figures in the manual.
I think these will be 352-0100-00 "Holder, variable resistor", as in Fig

Don't know what they are called but they look like a 'cable clip' for routing cables.

That's great material. Thanks to whoever uploaded it.
It refers to a couple of mod kits for early 530/540 mainframes, which I'd like to apply. Does anybody know what 040-0403-00 and 040-0404-00
