Title: Volume Control Post Speedball
Post by: adydula on July 30, 2015, 01:30:45 AM

OK the speedball upgrade is in now for a few days and its working fine.

Before I did this I added the voltage divider for the RCA inputs / volume control to get more range in the volume pots. the 75K/33K arrangement.

Now with the crack it seems that we are back to noticing the volume control in the lower postions with most material ie like 9 o"clock for most listening .

Is there a recommendation to adjust the gain or change the resistors to make this so I can use most of the pots again??

Thanks Much!
Alex

Put another 33K resistor across each of the 33K resistors that you already have in the amp.
