Just out of curiosity, regarding the Cathode Chokes on...

83.97.160.213

the Lux amp. Are these stock units upgradable by some other product. Sonicwise is the difference noticeable?

Halo Raul. A different choke might have a different DCR (will affect the voltage balance, and therefore, some involve alteration of PS voltages for the driver stage) and different L (therefore, different X of L). Both of which will change the operation of the driver tube (the parallel 5687.

  Thanks GTcharlie,
  
  I was thinking more of an upgrade within the same parameters. I've seen that there are some Silk Chokes on the Diyhifisupply web and I was wondering if they could be better sonicwise.

    Hi Raul
    Silk doesn't have an off-the-shelf choke that would be suitable, however the very first pair we made used some custom wound Silk chokes. Since then I've tried 3 different chokes (nothing exotic though) in that position and not noticed any difference. Possibly if we did a direct A/B we could pick up the nuances but we haven't done that. I also like to swap components to go higher but that choke needs to have the right l and dcr balance or it means tweeking the circuit since that stage is direct coupled. That means getting them custom wound and even then the dcr might be off.
    I guess I will try that at some time in the future.
    Watch for our soon coming monoblock Lux which has a whole host of significant upgrades AND using the 310a driver.

      perhaps a choke with higher L might spell a bit of difference ... But then you have to check power supply first to ensure correct + and - voltages.

        As is it is it models and measures flat. There is a delicate balance of L, DCR and size that needs to be maintained.
        I was thinking to try some more exotic cores too.
