Item 1:
USED low hours - look like new, 8 units marked "PHILIPS 6CA7", black base, original Philips boxes, crimped ribbed plates (3 crimps per side), 2 slots in plates, single large halo getters, glass has join in top, emission test at around 100% new tube spec. @ $US60 ea
Matched pairs available @ USD$150.00 per pair.
Please note I am currently testing these tubes in my stereo (3 pairs per channel in ultra-linear connection @ 330v B+) and they perform extremely well.
These tubes sound fantastic with their original Mullard/Philips clear
sound, superb transient response, tone and power.
