Excellent Tung Sol 5751 valve, made in Russia, and a godsend for people needing a top quality 5751 preamp valve. Great for harmonica players.
Please note:
Sometimes amps can use a 5751 in place of a 12AX7/ECC83. Some players prefer the way the 5751 colours their sound and changes the way the amp performs. This is purely a matter of taste. The 5751 is a lower gain tube than the 12AX7/ECC83S. That said, this swap doesn’t work the same way in all 12AX7/ECC83S loaded amplifiers. In some extreme cases, the lower gain of the 5751 can cause high distortion or not work properly at all since it has a different biasing point than ECC83/12AX7 valves.
We have tested these top quality valves, and each has a sticker on the box showing the results when tested with 250 volts on the anodes and a -2 volt bias. We test them on our suite of quality AVO and custom-built valve testers.
Another alternative is the EH 7025, which is more compatible with ECC83/12AX7 valves. We also stock the JJ 5751.
Includes a 180 day from receipt warranty (excluding user-caused mechanical damage) for peace of mind.
