That's funny, I used to live there too.
Really nice work on the mod. I was contemplating tackling the same. I see that you used Clarity ESAs rated at 630V. I don't know if the 250V ESAs were available at the time you did your mod, but they are available now, and they are cheaper. I checked out the crossover in my monitor 10Bs, and the highest rated cap was the 250V 12 microF Mylar. So,
1. Do you believe that the 250V version would be adequate (I.e. not blow up)?
2. Would it sound similar to the 630V version?
3. What advantage would the 630V have over the 250V version (I don' usually listen to really loud music)?
Thanks for any forthcoming clues!
The 250 volt will be more than enough, and I'd venture a guess that most of the old caps in there now are 100 volt.
Sonically, I can't imagine any real difference between the two.
If you're doing the TL Mod, pay close attention to the Hi-Pass Shunt Inductor, The only available inductor was the Jantzen, which was one gauge thicker, so the resistor that follows was increased to 3.0 ohms to compensate.
In one of these threads, a guy had pulled his polyswitches and measured their resistances in the 1.3 to 1.7 ohm range. You and others have settled on replacing the PS with a 0.5 ohm resistor. Just wondering how that value was settled on?
As I said, they're selling off whatever inventory they have left of the ESA 630s, and the SAs
I saw your note about the RDO-198 inventory - bummer. Still getting my ducks in a row, tho. The M10-SL3000mod schematic has a 2.0 ohm resistor that is slashed out and handwritten in as 2.7 ohm. Can you confirm that this resistor value should be 2.7 ohm?
If it is 2.7, Parts Express has a Dayton that would work. Are Daytons good enough - most people seem to like Mills?
Thank you again.
You will need the following resistors: 0.5 ohm to replace the dodgy polyswitch, 2.7 ohm to replace the 2.0 ohm, and a 3.0 ohm to replace the 2.7 ohm in the shunt, which is required to maintain the overall resistance of the shunt after you replace the .4 mh inductor with the .27 mh inductor.
Do not try and save a dollar here on that sandcast resistor. Mills are cheap and very good.
Not sure how I missed this one....excellent job!
those look nice
