Andy (Vintage Tube Service) is the best I have experienced within the US, but he has some limitations. He’s pretty old school too, which is fun but don’t expect instant gratification. I’m surprised Tube Depot would sell pulls as NIB/NOS- I don’t question your experience, that’s disappointing. What I got from them was pristine, but at the price-- for what I regarded as a common tube that I used to buy for 10 bucks--I’d expect the real deal. Being a "tube" audiophile is getting more difficult.
I’m actually considering a small solid state amp- possibly a Valvet- to substitute for my Lamm ML2s when I’m listening less critically. It’s supposed to be a good amp. Hard to find 12 watt solid state amps these days made to a quality level.
