Russian made reissue of the original Tung-Sol. The 5881 is the electrical equivalent to types 6L6 and 6L6G except that the plate and screen dissipation ratings have been increased approximately 20 percent. It embodies a complete mechanical redesign which results in greater resistance to shock and vibration.

IVE detected a "meme" in reviews of this tube - "great overdrive" and "warm" ..6L6GC tubes in low powered Tweed amps are going to make it sound "cold" or even "thin" or "brittle" because it takes a lot of current to over drive the 6L6GC -but they will give a lot more clean headroom, and thats why Fender installed RCA and GE 6L6GC tubes in so many of their amps in the old days.....5881 tubes were the old Tung Sol industrial service/military version of a 6L6GB , a lower current tube that can be pushed into over drive much easier...They were installed in Tweed amps, especially the Tweed Bassman for a couple years and the result is history. Marshall copied a 5881 equipped 1960 Bassman to develop the legendary Lead series amps and all because of that crazy screaming overdrive ..Incidentally 5881 tubes weren't readily or easily available in Great Britain until years later and so Marshall tried the KT66, but then switched to EL34 tubes to get that saturation and compression which all the hip London Guitar players wanted from the, once very, very hard - to - get - in - England Fender amps.....This is one of the Russian tubes that really deserves the praise it gets..This Tung Sol 5881 is obviously the result of old school American engineering and design applied to new tube manufacture..For a number of reasons (very few of them having to do with quality, or the wants and needs of the tube buying public) such concern for a product and for the end-user of the product is RARELY seen in the present day tube industry...WELL DONE ELECTROHARMONIX...golf clap.

I had Winged “C” 6L6GCs in a ‘57 Pro that made it sound cold. I replaced them with the Tung-Sol 5881 reissue pair and love it. It’s a warmer and more musical tone.
Try ‘em

Tweed and Brown Tolex Fender amps. Modern Fender amps. High gain Marshall amps where you'd like Marshall compression and crunchy attack, and sustain but some glassy 6L6 sparkle in the high and low ends. These are an excellent 5881 with actual 5881 ratings and performance - not just a 6L6GC in a short bottle.

If you're looking for a good pair of tubes to play clean guitar through, or want easy access to 6L6 sounding distortion, these are good tubes to try.

I bought these to put in a guitar amp build of mine. They came matched by the new APEX matching system which is a plus. I biased them to 19W per tube and let them burn in for about an hour. When playing they sound really good and have a nice balance of low end, mids, and high end. Notes come out articulate and there's not a lot of fuzz. The pair I have aren't very noisy at high gain settings compared to some of the other tubes I've tired.

In the end I am very impressed with these and I might make these my go-to tubes.

I have been using these in my Victoria amplifiers (45410T, Victorilux, and a Golden Melody) for a few years now. They sound great, very low noise, and they seem to last awhile. I have not received a bad one as of yet.

I found what I needed, place my order and was surprise how fast I received my electronic parts.

Thank You, AES

I buy and sell amps on a regular basis. While doing this, I ran across a deal on a Victoria Victorilux 4x10 model that had two Tung Sol 5881's in it. This amp sounded amazing. So when I had the chance to by a Victoria 45410 (Tweed Bassman) I jumped at the chance. It sounded pretty good as well but seemed it was missing something. I checked the tubes and found a Chinese made 5AR4 rectifier tube, along with another brand of 5881' power tubes. I replaced the 5AR4 with a Mullard, and replaced the outputs with the Tung Sol's. This made this amp come to life! It sounds as good, actually a little better than the Victorilux. The Tung Sol's have approx 30-40 hrs on them, they sound very smooth, and break up oh soooo sweet when driven. You can't go wrong with these!
