The new production Mullard branded EL34's are good and I've used them in my Audiomat to great satisfaction. The Psvane EL34PH (only sourced from Grant Fidelity vs. Ebay) however, are outstanding. Their 12AX7 is a very fine hair away from sounding like a NOS early 60's Telefunken. They are pricier than most new production tubes but, less than NOS.
As to my previous comment, Ebay Psvane tubes are seconds and anyone who has reported reliability issues confessed they ordered through this source. These seconds are dumped on the Chinese market which I don't understand at all since it erodes their image for a quality product. BTW, I have no vested interest in Grant Fidelity but, they insist on better screening.
