Just a quickie thread on ECC-83 valves in one of my headphone amps with my AT W-5000 headphones exclusively.
Amp...Vincent KHV-111 with a single 12AX7 (ECC83) valve (original JJ) and solid state output. Headphones...Audio Technica ATH W-5000. Computer DAC...Schiit USB Modi. Wires...Pangea USB cable and Kimber Timber interconnects from Schiit Modi to Vincent headphone amp. Abbreviation N/M used in mini reviews below shall stand for non-micro-phonic.
Tubes I've used and their ranking:
1. Amperex ECC-83 date code March, 1958. Using at present and for the foreseeable future. N/M
2. Telefunken ECC-83 date code mid 60's. Slightly micro-phonic but lovely bass and extended highs. Yesss.
3. Mullard ECC-83 date code Nov., 1957. Love it...after the Amperex/Telefunkens above. N/M
4. CBS/Hytron 7729 date...mid 70's. Use in analog aircraft electronics and sounds rich and detailed. N/M
5. Sylvania 12AD7 date...mid 60's. One-off design...superb. N/M
6. RCA/Command 5751. Broadcast quality valve and is clean, clear. N/M
7. RFT ECC-83 date...mid 70's. Muscular, definitive and extraordinarily N/M!
That's about it for my ECC-83 valve collection for the ones I swap in and out at any particular time. In the ECC-83 box 'o' tubes are also fine sounding tubes from G.E., RCA triple mica black plates, Tung-Sol, and some 7025's also. All 12AX7/ECC-83 valves I have except for some modern original equipment Chinese, are NOS (New Old Stock) German, Dutch, U.S., British made. I've been lucky to have found some the more esoteric valves listed above, even calling around small-aircraft repair shops locally. The pay-off is that tubes sound different in selected gear...and that has been a fantastic find for me, especially when the difference is mind bending-ly good!
