Counterpoint 5.1- Beyond My Comprehension

I just experienced good news a moment ago- my Counterpoint 5.1 preamp is again operating properly. I had experienced greatly diminished volume in my system. This happened suddenly- when I powered everything up an placed an LP on the table, it was barley audible. All other selections were lower also.

To make a long story of tube swapping, amp swapping and speaker swapping short, I replaced the CA4 in the power supply and all is well. It appeared to have a smoky band around the center of the tube.

Does anyone know why this caused a reduction in volume instead of a total loss of volume?

Thanks in advance!

Johnsonwu is correct. The Counterpoint regulators seem to be an issue now that the units are getting older. Either Johnson or myself can repair the Counterpoint units and we are both listed on the Alta Vista Website.

Happy Listening.

Same as what JWu said. One big improvement with the SA-5000 is the Direct In modification. I found that the sound stays close to what you hear now except the sound opens up and is clearer like using windex on your windows. It takes so much time to take apart an SA-5000 but worth the effort IMO if you choose to go down that path.

If you want to get it up and running either email JWu or myself from the Alta Vista website. JWu is in CA and I am in NJ.

You may also want to mod the power supply to a pure tube set-up.
