Opposite of what a previous poster stated and I hope this is not cause for concern, but I noticed that with px-4's, to get 4v I am at the very minimum of the voltage pot. No fluctuation after even several hours of warm up. Sounds fine to me but wondering if anyone else has had this.

I have a Salamander rack sitting on carpet, only the stock rubber feet. Something tells me I'm going to have to buy the spikes so that it sits more level ~ the gauge is maybe off-zero because it's not perfectly level.

So to clarify further. I have a Salamander 5.0 rack on regular old carpet. The rack is really hard to get level simply because of the way it's structured and on carpet it really is a crapshoot even though the PSU is on the bottom level now. I adjusted my 0 level a while ago and didn't really think through the whole non-leveled issue and it only occurred to me now that I really should make the rack as level as possible here.
This morning I ordered $60 spiked feet (highway robbery) for the rack to hopefully settle the leveling issues and hopefully that is what's the root cause for this discrepancy. Luckily I had it set at a lower voltage than a higher one for the sake of the tubes.
I also believe that because turning the knob a tiny amount has such a small affect on the position of the dial it means that being off only one notch could be almost a 1/4 turn.
I suppose will update when these spikes come in!

Does anyone ever use KR 842 VHD tube?
I find this tube's filament voltage is as same as the 300B, but the filament current is more than 300B (1.8A>1.2A).
If I switch the amp in 300B mode, will it be ok with the tube and the amp?
Looking for something like a Mullard ECC35 but with more pronounced mids. Love the clarity of the ECC35 and bass. Treble is a bit lit up at times. Any other suggestions ( of tubes that I could buy now) would be appreciated. The Tungsol BGRP in my profile sounds a bit bloated. DAC is now the Auralic Vega.
