hi Rick, I have the Pre Box as well. How did you connect the Linear power supply you bought? Were you able to source a connector or did you run cables into the box to connect t?
So I bought a Pro-ject Pre Box RS... (Valve suggestions?)
The Pre Box RS comes from the factory with
Electro Harmonix 6922, on the output stage.
All I have read about this pre has suggested a linear power supply upgrade and tube rolling gives
significantly better results, so the linear PSU is already done (19VDC from a HDPlex 200W).
I've already got some tubes I bought for my old old DAC (it's now 9 years old).
I have a pair of Amperex P.Q 6922 [VCM 163 tested], and a pair of
Phillips E88CC SQ [1109] with writing on the box [12500-12750 and 12400-12500 on the other box] What do those hand written numbers mean?
Anyway, which valves should I likely go with? (I am hoping for longevity as well as quality)
