Is 5881 same as 6L6?

You can immediately notice that the 6L6 and 5881 are in the same family of valves. They are part of the general evolutionary process for this particular valve. So they are similar, but not identical tubes. In other words, there are no 6L6 tubes which are identical to the 5881 tube.

Are 6L6 and 5881 tubes interchangeable?

In many cases, 6L6s can be safely substituted for 5881s, but not vice versa. In a few cases, where the plate voltage tolerance is high enough, 5881s can be used in amps designed for 6L6s.

What tubes are interchangeable with 6L6?

For the most part, 6L6 tubes are interchangeable. The 6L6 along with the G, GA and GB are all rated to the same 19 watt plate dissipation with 360 plate volts. This one is a GC with 30 watts plate dissipation and 500 plate volts.

What are 5881 valves?

The 5881 valve (5881 tube) is a power output tube used in some makes of guitar amplifier. The 5881 is towards the lower end of the power spectrum for output valves. It can handle a maximum of 23W and so a pair of 5881 valves would give you about 46W tops.

What are 5881 power tubes?

5881 is a beam power pentode with a maximum plate dissipation of 23W in the classical short bulb. It is very similar to the 6L6 sound but with less power. It can be used in any 6L6 amplifier.

Can I replace 6L6 with KT66?

6L6 and KT66 are essentially the same tube, but depending on the 6L6GC and KT66 being compared, the 6L6GC might be smoother, while the KT66 might be a tad more aggressive.

Can a 6550 replace EL34?

The 6550 is cleaner (if you keep the PI the same), wider bandwidth and has a slight scoped mid feel compared to the EL34. My personal preference is for EL34s but many do like the 6550, especially for sparkling cleans and more metally type overdriven tones.

Can 6L6 replace EL34?

Assuming you have 1k screens and your sockets are wired for El34s like in a typical marshall yes you can run 6L6s. I can run 6l6, 6v6 El34 and KT88s successfully in my 50w plexi. All you have to do is check the bias.

Why are Matchless amps so expensive?

One of the reasons why so called boutique amps are so expensive is that most of them try to use the same types of high quality transformers, caps, tubes, etc. which are getting harder to find and/or more expensive to have made.

Is 7025 the same as 12AX7?

Re: 7025 vs 12ax7 – which are the differences? None. The 7025 is allegedly a low-noise 12AX7. The best 12AX7 is probably quieter than the noisiest 7025 but it’s the same tube.

What’s the difference between a 6L6 and a 5881?

Pushed into distortion there’s less grit here than in the case with their bigger brothers. Far as I can tell, 5881s generally have a tad more mids than 6L6s, and have just a bit less high-end timbre. A typical 6L6 will usually have a bit more headroom as well.

What’s the difference between a 6L6 and an EL-84?

The EL-84 and 6V6 are popular in cheaper and/ or low power amps and sound very vintage by comparison – nails the blues sound. Pushed into distortion there’s less grit here than in the case with their bigger brothers. Far as I can tell, 5881s generally have a tad more mids than 6L6s, and have just a bit less high-end timbre.

What’s the difference between a 6L6 and a tungsol 5881?

Location: Port Angeles, Washington. One deciding factor about using 5881’s or 6L6GC’s would be the plate voltage of your amp. The following came from “The Tubestore” website (referring to Tung-Sol RI 5881’s): “The Tungsol 5881 is a 23 watt tube and is rated for a maximum plate voltage of 400Vdc.

What’s the maximum plate voltage of a tungsol 5881?

The following came from “The Tubestore” website (referring to Tung-Sol RI 5881’s): “The Tungsol 5881 is a 23 watt tube and is rated for a maximum plate voltage of 400Vdc. The many amplifiers that have higher plate voltage but use a tube rectifier can use the Tungsol 5881 tubes without issue.
