Hello all. I have a few questions about components especially output transformers for a 6L6 clementine. I would like to be able to integrate this into my current system and be able to swap it in and out with other amps for comparison. So here is a little bit about my system.
My main speakers alternate between two sets; ESS AMT monitors 6 ohm minimum 87db and Klipsch KG4s 4 ohm 94db. My source is a blue ray player for CDs. I am using a khozmo MKII 10K passive attenuator to control volume and a MyRef FE amplifier. I have a polk PSW505 sub that I use to supliment the shortcomings in low end for the AMTs. All of this resides in a 12' x 12' listening room that opens up to two other rooms, not ideal but it works.
Idealy I would like to be able to just be able to swap this with the MyRef and be plug and play. These things tend to never be that easy........
My first question is about the speakers. The schematic calls for 8ohm edcor output transformers but my speakers are 4-6ohm. In my previous amp builds I selected lower voltage transformers to acount for the lower impedance but this is not quite the same thing. Do I need to select a different part number to account for the lower impedance of these speakers? Can I even use one part number with both speakers, or should I pick 4 or 6 and go with it? Should I even consider using the clementine with the 87db AMTs at all or will I be surprised?
I promise I searched all morning on this site and some others and never really found the suitable answers
My next question is about the passive volume control that I am using. It is a khozmo MKII 48 position stepped attenuator. It is the 10K variety. I thought tube amps typically liked to see higher impedance like 100k or more, but I could not find anything definative. Will I still be able to use the 10k khozmo or will I run into trouble with it?
Im sure I will have more questions but these are the main head scratching issues so far. Thanks in advance for any insight.
