Carbon Comp vs Metal Film

I like CCs b/c they are non-magnetic, non-inductive, and handle surges very well.

And they're just so bloody simple. No end caps and whatnot. Just lead/resistive element/lead.

Also, I think they're just plain beautiful.

They look like commie components built like tanks Wave! Built to survive GI Joe's onslaught and take over after the precision US Vishays have all melted away...

Not nearly as beautiful as CCs though.

US Vishays?

Vishay is the name of Polish village where the founder of the Israeli company was hidden under the floor of a house where German soldiers stayed. There were few of them, so he being a kid could learn in that underground physics and math from a grown up man who was an electronics engineer (AFAIR). His dream since then was to survive and take over Telefunken.

Actually, MLT resistors indeed were manufactured for Soviet army. Non-magnetic metal film. Blue one is covered by a fireproof paint. The rest if to burn a paint stay naked. I don't mind to have naked resistors in the gear for myself (it reminds me they survived great abuse, after that are more stable and proven to be reliable), but people usually don't like them. :)

Woah, I wasn't aware of that. Felix Zandman - Wikipedia, the free encyclopedia
Pardon my ignorance, but I assumed that Vishay was from India...

P.S.: Wavebourn, one more question: Up to what voltage do you trust your MLT resistors?

I use 240K MLT-2 resistor for feedback from GU-50 anodes to anodes of driver tubes (about 500V DC +/- 750V swing)

And in a pinch can be crafted into miniature pipe bombs. :D

No bombs, but great lighters: pliers, peace of cotton, and 220V outlet, when I was out of matches. :D
 
Carbon comp's

I must admit I havent touched valves for 35 years (flip!!! is realy that long) So I'm just a tad rusty. I didn't know you could still get carbon comp's

This may or may not be a silly sugestion, (and no, I haven't tried it myself)
but, carbon comp's were alwas baked in the old days, maybe they just need a bit more baking, after all, that is probibly the most expensive aspect of them, and I wounder if the manufacurers might skip abit on it?

Might be worth a try, just bake them over night in a low-ish oven and put a meter across them the next day and put a lable on them with thier new value.

Just a thought!!
