Constant noisy tubes maybe go solid state?

@ gochurchgo. Very easy solution. Go Here http://tubeaudiostore.com/ ,
and look up your tubes. There will be three grades. Standard, Low Noise and Super Low noise. the SLN tubes are one in ten. Each tube is individual tested and a label with the important specification is placed on the side of the box. The SLN tubes are expensive but the SLN 6922 I got were an easy 10 dB quieter than the one ARC supplied with the phonostage. I am on my second set now and they are just as quiet as the first.  Basically you now exactly what you are getting and pay for it. Roger Modjesky created this process. He passed not long ago but his business soldiers one probably in the hand of his employees who really liked him alot. Several are contributors on this site. 
Everything else, all the NOS stuff included is a crapshoot. IMHO these people with their NOS tubes and Tube rolling are insane. Perhaps it is the tube rolling that made them insane. Many give up in frustration and switch to SS if they have any money left.

By wary of any tube seller that uses the term: "NOS in white boxes". Much more common with JAN tubes that were bulk packed, this term usually means that the tube tests as NOS and comes in a white box. Not the same thing. 

Brent Jessee sells high quality tubes. The catch is you must request noise testing; it's $10 per pair I believe. 
Depending on the circuit in your component you may need to use low-noise tubes. I only buy noise tested NOS tubes.

Andy at Vintage Tube Services includes testing for noise and microphonics, Upscale does as well.

Thanks. But like at Tube depot, they have an incremental charge of $4 for "Low Noise & Microphonics" which based on your description would seem to be binary or incompatible....? Is this a good option to choose ?

And next, when we use the term quiet or noisy are we talking solely about the hiss in the speaker drivers ? Really a nob question 😞

Help me understand why you think you need to be wary of NOS in white boxes from reputable tube dealers. I’ve had a NOS NIB RCA 12ax7 fail, and just had a New Production Psvane KT88 NIB fail after 300 hours. Any tube can fail regardless how they were packaged.
