Congrats on your FS purchase! I've found the Amperex NOS tubes to be outstanding. I have 6922s and, 7308s, both PQ and USN. Some are Holland, (under the Philips lable) and some are USA made. All are white lable. These are sonicaly even, clear, extended and seemingly un-colored. Emmanuel, at last communication, seemed to like the less expensive, and currently produced Electro-Harmonik tubes. Sadly, these (EH 6922 Gold Pins) don't seem to work as well in my system. I still have apair just sitting here. :( Email me if you want them. I have also tried the Ei 6dj8, with good results. These are very surprising, considering the cost is about $20 for a pair! They are not the same as the NOS Amperex tubes, but at 8 -10 times LESS than the Amperex, they are pretty darned good. good luck with your new toy. :-) paul |
I've tried Siemens 7308 "D" Getters (1965), Siemens 6922 "D" Getters (1959), Amperex 6922 PQ USA White Label, and Amperex 6922 PQ Pinch Waist "D" Getter, and Phillips 6922 SQ in the First Sound Presence Deluxe II. I preferred the Amperex 6922 PQ USA White Label tubes. They have bass equal to the Siemens, and are equally extended, but they have a slight midrange bloom, which I like. The Amperex 6922 PQ Pinch Waist tubes were not significantly better than the Amperex 6922 PQ USA White label tubes, and therefore I could not justify their exhorbitant price. The Siemens are excellent, with the flattest, most neutral response across the frequency spectrum, but I found their sound to be a little hard in the upper mids and highs. The Phillips 6922 SQ have a slightly softer top end than both the Amperex and Siemens tubes. This is all subject to personal preference. If you haven't already read Joe's Tube Lore, then I'd suggest doing so. While his is only one man's opinion, he has been spot-on in my opinion. |
