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.
Balancing Act Tube Rolling - Page 21
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.
