Why so many caps one? I thought only 2x 5uf input caps, and 2x 0.12 decoupling caps?
Actually I'm interested to built one also, wanna see how this grado version of cmoy sounds?!?!
For more information take a look at this:
http://hi.baidu.com/%C5%BC%B6%FB%BB%A7%CD%...bbca130c57.html
This website also stated that the orginal RA1 have a gain of (465/122K)+1 :gain of 1
, and some clone of ra1 uses a gain of (465K/122K)+1 :gain of 4.81
which makes the amp sounds different.
By the way, anybody knows where to get 5.1uf Solen caps, i have search ebay, i can only find 4.7uf...
Thanks
