According to Mesa Boogie, if you order these tubes with "middle values" you should not have to rebias your amp.

Will I have to rebias my EVH 5150 III Amp if I put these in.

If your EVH has a bias pot we recommend re-biasing your amp.

You can request plate current (PC) ratings of low, medium, or high where high equates to high headroom. Simply put a note on your order or give us a call and we can accommodate your request.

Hello Good People, This is Dave. I have four JJ 6L6GC's with a sku #T-6L6GC-JJ-MQ They were given as a gift bought thru amazon, And am happy with them! My question is, on all four tube boxes a label was marked 17/2.5 Could you tell me what this means? The values? Thank you in advance,I would really appreciate it! I will look to "Amplifiedparts" for future tube/electronics needs. Best Regards, Dave

The number will mean different things depending on how it is written. You will either see a printed Apex sticker or a sticker with a handwritten number. Please contact us at: info@amplifiedparts.com for more information.

Power tubes need to be matched in order for your amp to operate properly. If you ordered your tubes from us, we can get you one tube to match your existing power tubes.

If you require two power tubes in a push pull configuration then you would want to purchase a matched pair.

Yes, we do have a complement for the Twin Reverb and you can find it by searching this part number on our site. SET-FENDER-123

With any retube, you may need to make adjustments to your amp depending on the type of bias it has. Your amp will either be fixed adjustable bias (has bias pot on the back of the amp) , Fixed non-adjustable bias (bias is fixed by a resistor in your amp), or cathode bias (self biasing no bias required). The manual for your amp should be able to tell you what type of bias you have. Rebiasing an amp is something that should be done by an experienced tech. Many amp manufactures setup their amps to accept "middle values" for tubes. You can request middle numbers when ordering. Keep in mind, this will not guarantee you will not have to rebias your amp.

Yes you will want to request "high numbers" in the notes section of the checkout process.

This will safely work in place of any 6L6G tube.

According to our research, the Crate V50 does use 6L6 power tubes, so yes, these are compatible with that amp.

6L6 tubes are interchangeable with 5881s, but a 6V6 is not compatible with the two.

This matched pair solved all the issues I was having and improved the tone for the better.
Much better!

Great sounding tubes and well-matched. However, the gain is on the low end so I had to increase my bias adjustment to maximum in order to get close to the recommended 70% of maximum power output from the power tubes.

I installed a matched pair of JJ 6L6 GCs in my 1963 Lafayette guitar amp. They produce great sound on both highs and lows.

Put a pair of these in a hot rod deluxe III. Very open sounding with controlled bass, mids are super and nice high end without super piercing highs. Really gave this amp some balls.

From my experience with the JJ 6L6GC,the short review at the top of this tubes' page is spot on.If you like dirt (and who dosent) This might be the best new tube you can get for it.

This is the best 6L6 I've used... so far. It really gives me a smooth, wet sound in my 50W guitar amp that's quite noticeable compared to other brands I've tried. My current pair are going strong and it's been over a year since I installed them!

These are very clean sounding if you like that.
