see if you can find the output voltage in the manual.
Or you can go to radioshack (if you can find one) and build a cheap but good attenuator.
15k 1/4 watt metal film in line with a 100k volume pot shunt to ground. Very simple.

There is another possibility - the seller who upgraged this amp used silver wiring inside. I wonder why? Silver wires can make the amp sound thinner and exaggerate sibilance...
In addition, EL-84 tubes have more HF focus than, say, EL-34s, which may add to the problem.
I think the silver wire you are seeing is the 600v teflon coated wire. BTW excellent wire!
As for the EL84 vs EL34 differences, that is due to more of the amp design and component matching.
You can try this. Inside the amp put a 15K resistor in line with the CDP input signal and a 20k-ish resistor to it's ground. If that improves it even a little then you're on the right track.
