Ergo Uber-Cole Q

JoshK · 13th May 2011, 03:25 PM

Can the uber-cole use D3A's in the output spot? I've been eyeing this phono stage, not really wanting to build my own. However, I have plenty of D3A's but no 6688s.

It would need the Bias adjusted. Write to Simon and ask if you can send a pair over to be fitted and the adjustment made, if you buy it.

Note that a D3a will give nearly 6dB more gain.

thanks Thorsten. I somehow thought the mu (triode strapped) was similar but I see it is different.

It does not mean the D3a cannot be used, just that the circuit needs small chages and that you will have nearly 6dB more Gain.

Also, I noticed that there is one MM input and one MC input. Can they be used simultaneously, with a switch or something. I have two arms and was thinking of using my existing HOMC and obtaining a LOMC for the other arm.
