With tube gear its source or sources on first, then tube preamp (volume all the way down), or buffer stage, then let the tubes warm up a minute or two, then turn your amp on either SS or tube. Shut down is in reverse order with the volume all the way down. Turning a tube preamp or buffer on after the amp is turned on is never a good idea. It usually does cause various unwanted noises, some very loud.
I use 6P14P-EV's in my ST-35 as well. They're actually the same as 7189.

I agree. If they're going to sell tube based equipment they should have that in there instructions. For a lot of people this is there first introduction to tubes since Schiit's tube gear is very affordable. You can get away with turning sources on after startup in most cases though. I've just made a habit of turning on the source I'm going to use first before the preamp, then amp.
I use them in my Glow Audio Amp Two, with 5751 drivers. I suspect we may be getting them from the same Ukranian vendor. They seem to have more sparkle up top and more bass control. I'd rotated them out in favor of the stock Shugang that came with the amp, since I was only using them for mid frequencies. When I rotated that amp into my mono setup, I was reminded how lousy those Shugang were, with rolled off bass and a thin and tinny sound overall.I use 6P14P-EV's in my ST-35 as well.

Pretty much the same tube as a EL84, but can handle higher Voltages.
The 6P14P-EV's are ruggedised longer life versions.
Ya, thats a lot of gain.

Possibly yes, since the preamp is passive. But I can see where the Buff could make some noise when first turned on and engaged before the tube heater gets hot enough to let the tube conduct and stabilize. Heaving the volume all the way down on the preamp can help to especially if the passive preamp happens to be connected after the Buff.

Tube Depot sells a 6SN7 adapter, but evidently it's too big to properly fit the tube opening in the Buf cover. According to this Head-Fi Post, there's a Head-Fi member that makes awesome custom adapters, and can make one for Buf. You'd have to contact member Deyan directly through Head-Fi to order an adapter. So, I guess you'd have to join that forum for the ordering process to happen.
Ordered adapters for 6SN7 and 5670 tubes. Cheap enough and I already had the tubes.
Good to hear that you have a positive review of those tubes. My matched quad should be arriving from Ukraine tomorrow.
Another nine pin that I'm using in my Freya N is the 6CG7, mine are NOS Raytheons made in Japan. I find them a bit livelier than the stock soviet 6NIP. They are said to be like the 6SN7 electrically.
