Another common ground question?

I am inquiring about two power amps.
Nikko alpha 220
Yamaha Mx 600
Does anyone know if either one of these are a common ground?
I don't have them, so I am not able to check them out .
Thanks.

    If you plan on using either with SDA speakers (pin blade only models) it doesn't really matter as long as you use a Dreadnought.

  • Between the two amps , which one would you recommend? Both are 125 wpc into 8 ohms. If I purchase the alpha 220 , I will purchase the beta 20 preamp and replace my existing Rotel RA870BX.
  • Where can I buy the parts , and what are the costs involved to build a dreadnaught?
    Can you purchase one already constructed? And where?
    Thanks.

    Download the handbook, a lot of the links in the thread no longer work.

    Attached is some DIY information. This works for the stock 800KVA Avel-Lindberg Transformer which you can order off the shelf, or the custom ordered 1000KVA one. In the second doc DarqueKnight should have attribution for most of it as it is clearly his work. I downloaded this info as insurance against a time when it might not be accessible via the forum. Who knew?
