VAC owners, sound off

There is no better NOS seller than Vintage Tube Services. Brent Jesse Recordings is also very good. I agree with Swampwalker, you don't know what your doing, stick with VERY reliable and known sources.

The VAC selected tubes are excellent IMO but if you must play with NOS then Andy at VTS is the one. You want the lowest noise and best matched tubes possible. Andy has never let me down in that regard.

At this point I'm stoked to reverse polarity and see what happens, tube rolling may be a moot point. Thanks for the tips and troubleshooting all. Let you know what happens. If it is the 'a ha' moment, I'll be one very happy puppy.

Appreciate the tips on tube buying on ebay and such. I was going to go through a dealer called we-252 who runs a store called FantasticTubes, if anyone is familiar with them. Great feedback and a Power seller.

So in a general question, what's the deal with inversing polarity? Why do some manufacturers do it and not others? What's the advantage?

we-252 is the seller's name. Regardless, I appreciate all the "Beware of Ebay!" signs you guys threw up. My last tube purchases have been from either equipment manufacturers directly, or from agon.
