i have ton of hi wattage iskra 1K to 10k waiting to be used..for the moment i didnt use them in guitar amps.. what i will get if i put them in B+ dropping string? i have never think other than increasing the noise because of high current passages .. but i saw also dumble used them there...something i just refuse to copyWhopperPlate wrote: ↑Fri Sep 23, 2022 9:53 pm i shared this search list in another thread. Felt it was a good link to share here concerning finding modern available Carbon films for the B+ string .

Re: Non-NOS component choices
Imo iskra specifically in the B+ will make things noticeably stiffer and clearer. Strong. You know that feeling where the strings seem just a bit heavier to bend and the pick doesn’t glide as smoothly from string to string ? I don’t know maybe most don’t , but that’s what I felt in Marshall clonesbepone wrote: ↑Sat Sep 24, 2022 9:27 pmi have ton of hi wattage iskra 1K to 10k waiting to be used..for the moment i didnt use them in guitar amps.. what i will get if i put them in B+ dropping string? i have never think other than increasing the noise because of high current passages .. but i saw also dumble used them there...something i just refuse to copyWhopperPlate wrote: ↑Fri Sep 23, 2022 9:53 pm i shared this search list in another thread.

I like to mix them with other brands and compositions . Never tried em in dumble type circuitry

Re: Non-NOS component choices
i like "strong" and "heavy" sound.. but to be more precise i want to test Iskra CF's 2-3W.. wirewound from 4-10W not so...always i was connecting carbon film with "muddiness".. not clarity.. i have one 183 under tweaking, easy to find out
also bias leak will try too

What value? If low value, then just inserted in series with the dropping string?WhopperPlate wrote: ↑Sat Sep 24, 2022 9:10 pm Was thinking about other Non nos parts I have tried, and one interested power resistor were the Mills non inductive resistors . Expensive , but tank like ratings and it was pretty startling how swapping it into the b+ line determined the response of the amplifier .
Again , kinda like the takman effects on the signal path , I felt like I was under the magnifying glass . The amplifier slapped me around , felt like it had more output power because of the lack of distortion , not as bouncy and gainy, but the dimension was crazy . Not brittle , but wow was it loud in my ears and head . Stout was a word used to describe it .
That amp wasn’t mine, so it was changed to deliver a softer sound, but it’s something I want to try out again Soon.

Re: Non-NOS component choices
Simply using them in the stock values for any given amplifier ; for typical dumble 2k2, 22k, and 2k2 . I have even used them as the screen resistors. No additional resistors . Be cool to replace choke as an experiment . They come in large enough power ratingsdorrisant wrote: ↑Sat Sep 24, 2022 11:28 pmWhat value?

Re: Non-NOS component choices
I think it was talbany who said it already , iskra have a strong thick 2nd order harmonic going on and a big round bass“ . To me that roundness is fat low mid and meaty and pushes in a mix , but also lends itself to that collapsing bass sound that Marshall’s can get . The “clearness “ I mentioned is more like a high mid clarity , not exactly like a pristine open anything. “Articulate “ was a word used . Again, think classic late 60s Marshall. I get similar effects whether using them in the signal path or the B+ string .bepone wrote: ↑Sat Sep 24, 2022 10:33 pm i like "strong" and "heavy" sound.. but to be more precise i want to test Iskra CF's 2-3W.. wirewound from 4-10W not so...always i was connecting carbon film with "muddiness".. not clarity.. i have one 183 under tweaking, easy to find out

Re: Non-NOS component choices
Yes Iskra's are a favorite of mine. Similar to a Phier but has a clear/ cleaner midrange w/ the classic big rounded lows.. Love em!
Hey Charlie
Yes I do PM sent
Thanks
