And therefore the following below, which is 40mm wide would not fit?

So I'm considering the below:

Comments?

silkscreen is in scale - if you look it in 100% scale on screen 😉
anyway - on last page you can find Fischer numbers
download this :

and look
~ 4MB , but worthy

don't worry ......... he's in your footsteps , all the time .........

So Jacco, those resistors in the power supply you were talking about .. would it be better to use inductive wirewounds instead of non-inductive resistors?

negligible difference - use what you find in deepest end of your drawer ....... or stiva, whatever

burlesque(bər-lĕsk')
n.
A literary or dramatic work that ridicules a subject either by presenting a solemn subject in an undignified style or an inconsequential subject in a dignified style. See synonyms at caricature.
A ludicrous or mocking imitation; a travesty: The antics of the defense attorneys turned the trial into a burlesque of justice.
A variety show characterized by broad ribald comedy, dancing, and striptease.
Personally, I like the last definition!😉

Certainly not surprising....😀



P.s. I don't intend to carve the Pumpkin in the near future; However this has been one of the most enjoyable threads 😎

good one...😀
I just thought it amusing that inductive might be more desireable because they might in fact reduce ripple a little. and more expensive non- inductive would be worse..I know the amount is teeeeny though

ZM means that at the current level of the shunty it bares little significance.
Wirewounds have less noise, are sturdier, induction or induction-free has no bearing for DC-operation.
So if you got them, sure, use them.
But if you don't, use metalfilm, ever checked how much a low power wirewound resistor costs ? (e.g Dale RS series)

I've only been holding out on you, all due to consideration of your weak heart and you blood pressure 😀

ask your Nanny M.
Yeah we are even talking single digit watts here, no worries for quite some time.....and quite some time in this case just might be forever

Yeah, he is right at your tail.....blazing away 😀
Woodie, repeat after me: 200mA per coil!

wherez da preamp we are supposed to be making?
😀
I haven't seen my bench in 3 weeks - real life has a grip on me

All right, getting to several issues: besides my weak heart--I'll try not to stare at Mrs. Magura's pic too much.😉 , where are you putting the chokes? Did I miss some new schematics? Are you doing something like myself in the JfetBOZ project?
