Hey guys,
I notice that my amp distorts a bit when being driven hard. This is not my typical listening levels, but something I just noticed. Since I noticed this, and since my amp is a bit of a one off version of the poseidons, I decided to try several things. My amp shares a common PS for both channels.
I pulled my tubes on one channel out and cooked a cheap meter banana clipped to the b+ Yellow_Light_Colorz_PDT_02
This did not assist the distortion issue at all. I'm driving it with a 6SN7 preamp and the gain is a bit high for the amp.
My B+ sits around 496v at idle, and fluctuates down to as little as 475-470v during higher volume applications. Does this sound right? I have 130uf on each of the first two caps before separating the B+ for the driver tubes, so there is plenty of capacitance. It is also SS rectified so overdoing the capacitance is not as big of an issue.
Any ideas or tests besides lugging my 125lb towers :o into my tube area?
Thanks,
Blair
