fitz43's Phase Linear 700 B White Oak Conversion

[laatsch55]

Doug, the "B" arrived today in good shape. And a heartfelt "Thank You" for the goodies, was totally unexpected and stuff I can certainly use....

Hooked up the "B" and it's having a go at the horns. Doug, a fine sounding stock amp. One that no longer satisfies the ears after hearing the White Oak Version. The bass is not there like a WOPL, The highs are shussy. After Shpongle's "Are You Shpongled" It will get a complete suite of before testing. I can already tell ya how the Frequency Response will look.
