    Changing Voltage Setting of Larocco PSR

    Thanks.   I have switched it to:-     Did I get it correct?   Although board says 220v, transformer says 115v plus 115v.   Board doesn't state any fuse rating for 230v but I have got a 250v 1A fast blow in it. Do you happen to know what the fuse rating for 230v should be?   With the...

    Changing Voltage Setting of Larocco PSR

    Recently bought a Loarocco PSR but the voltage setting is for 110v. There is also a setting for 220v but the board markings are confusing to me. Can anyone help please?

    The Stax thread (New)

    I am a little concerned that the toriods might buzz; and if its under the amp, the tubes will not like the vibrations. Using additional neoprene bases will certainly help, but may not eradicate the vibrations totally. Best if the transformers are totally quiet and vibration free, but my...

    The Stax thread (New)

    Greatly understand what you are getting at. Keeping it to the solid state for the PSU makes a lot of sense to me as well.   I am really looking forward to this project taking off.

    Is anyone building the KGSSHV?

    I know people that have given up their dact for the khozmo. I have never heard the Khozmo but was about to buy it but did not due to reading about its problems.. I have consequently gone back to buying the DACT.

    Quote: If you use RCA you will probably ground the cold portion, which means there will be no signal from the cold. This leaves only the hot to provide the signal, therefore only have half the board pumping up the signal.

    I believe that technically, double the voltage swing as signal input is x2 as compared to RCA; because XLR is pull and push (hot and cold will pull and push the signal). This gives us double the power. Using RCA only means that only half of each amp board in the KGSShv is amplifying the signal...

    Yes, I use the DACT for my KGSShv. I have 3 more amps to build. 2 more than half done. I had placed an order with khozmo for 3 pieces of the round type but problems with their quality is forcing me to rethink for other choices.

    Infact my bread new DACT is starting to make louder "pop" noises as I turn the volume knob. Was there when I first installed it; then it went away as I used it more and more; and now (after about 150 to 200 hours of total use) the "pops" are louder than when first installed it. I have never...

    What alternative attenuators, besides the already mentioned DACT, can we go for at Khozmo's "level"?

    Thanks John. I stand corrected then.

    Quote: That depends. Amb site posted , "An optional sensing loop employing thermal breakers can be used with the ε24, so that in the event of device overheat, it will be automatically shut off". If you have that you should not need additional thermistor.

    Quote: Thermistor works by increasing resistance when heat goes up. That way as resistance goes up it will block big rate of flow (ie. current) before it reaches the transformer. If the heat goes too high for the thermistor it will melt - like a fuse. Inshort, it is an "intelligent fuse"...

    Quote: I would use 2 in series.

    John, 2 pieces of 2amp each in series. That should reduce the inrush current by quite a bit before it hits the transformer.  What are your thoughts on it? I believe Kevin did recommend this at the KGSSHV, Balanced Dynahi Rec A and Dynafet board run page 6.   I was also thinking of putting...
