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: [email protected] 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.

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.

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.

We typically have a range of low, middle, and high plate current ratings in stock at any given time for the JJ 6L6GCs. You can make any specific requests for matched tubes in the customer comments section of the checkout screen.

These tubes sound incredible in my 65 bandmaster,highly recommend the matched burn in they always fire up.I have JJs in all my Amps ,65 BM 62 deluxe And JTM 45 and they are great for Classic rock and blues,The only tubes that aren’t JJ are the PI which I use the Sovetek LPS

the tubes arrived faster than expected and were undamaged. What more could someone ask for? Maybe some mints or nuts included in the box. Yeah, I like mints, but I've digressed.

Great tubes. I use JJ’s in my fender super sonic 22 (6v6) and jj tubes in my hot rod deluxe (6l6). Highly recommend. Shipping is also done professionally, tubes arrive fast through usps and are packed to ensure they arrive in working order. Thankyou Amplified parts !

If you are looking for a good tube at a good price you have just found it! Good Sound at a good price. Everyone's hearing is different. So, We could get a lot of argument on this subject. I have found JJ tubes to be a very good buy for the money and have had no complaints from my customers that have gotten them from me. Don't forget: If you have had a sudden output tube failure always have the screen grid resistors checked! If they are bad - when you put your new tubes in the amp it will immediately burn them up! * Not worth the risk is it?

Best tubes. I re-tubed my EVH 5150 and I love how it sounds, more focused, tight, and alive.

EdG - March 9th, 2021

Amp had an intermittent solder joint at one of the 6L6GC screen resistors that eventually blew out one of the original Ruby output tubes. After finding and correcting the problem a matched pair of JJ 6L6GC tubes from Amplified Parts brought the amp back to life and is now better than new, sounding great with full bottom and top end. Thing here is that the tubes I received were matched perfectly when measured on a transconductance tube tester and when biased were within less than a milliamp of each other. Signal testing with an oscilloscope showed a very symmetrical both clean and overdriven output waveform, confirming the well matched tubes. This was my first purchase from Amplified Parts and will absolutely purchase again from Amplified Parts when tube matching is needed for any of my amps since the quality and cost amounted to a very good value. BTW this is an honest voluntary review and I have no affiliation with Amplified Parts. Again, very happy with purchase.

Solid tubes with crisp and clear performance for a reasonable price.
