I returned from the LA meet to find I had a bright yellow parcel with my name on it.
I've nestled them in between some Electro Harmonix 300B's the @randytsuch loaned me.
They are a big step up from the JJ's but I'm only 30 minutes in.
Finished my first flac track of them "thar rusky tubes" They sound like I'll leave em in long enough to see where the settle.
I'm impatient.... so that's a great sign.
