Fender Blues Deluxe - Blues Deville Max Headroom Option

Product Details

Want all the headroom possible from the front end of your Blues Deluxe / Deville? This is our Max Headroom Retube kit. It uses an ECC81 for V1 to drop the gain in the front end, an ECC81 for V2 to drop the gain in the drive channel and a balanced ECC83S for the phase inverter in V3. The default power tubes are the JJ Electronic 6L6GC’s but you can configure this kit to use the JJ 5881's or the JJ 6V6S's for a lower output and an earlier breakup from the power section by clicking on the "Customize" button!

With the JJ 6L6GC's this will get maximum power and headroom for you Jazz and Country players.

Note: If your amp is the original fixed bias non-adjustable version then stay with the JJ 6L6GC's or 5881's, we select these to run optimally in both the original-fixed bias Deluxe/Deville. The fixed bias point will be too low for the 6V6S's.

The Balanced ECC83S is located closest to the power tubes.

All Combo amp Retube Kits are shipped with the Eurotubes Double Mica 6L6GC’s at no extra charge. JJ Electronic started building us a proprietary version of their 6L6GC (the 6L6GC-DM) in 2005 with extra layers of mica. This reinforces the plate structure and all but eliminates tube rattle symptoms.

If you choose to go with 6V6S’s and you play by yourself in a quiet environment or record with your amp you may want to consider using the EuroDamper tube damper rings. These are available in the "Related Products” tab as a set of three and will greatly decrease tube rattle.

For the adjustable bias RI Blues Deluxe/Deville amps PLEASE!!!! READ THIS NOTE:

We say that you can go as high as 90mv at the test points for the JJ 6L6GC's. This DOES NOT mean that it HAS to be set at 90mv!!!!!! For maximum headroom we recomend a setting of 70-75mV as measured at the test point. PLEASE read below!!!!

We get phone calls and emails everyday asking why the bias has to be set at 90mV and the most asked question is "I can't get my bias to 90mV now what do I do?" Or "I set my bias at 90mV like you said and it distorts too early".

As we state in the video, you DO NOT have to set your bias at 90mV!! We consider anywhere between 70mV up to 90mV a usable range with 70mV providing more headroom and 90mV providing an earlier breakup. Some amps will not quite hit 90mV depending on the value of the final bias resistor and or pot. This does NOT mean your amp is broken!! the value of the components will vary.

YOU DO NOT NEED BIAS PROBES TO BIAS THESE AMPS! YOU CAN USE THEM BUT THEY ARE NOT NECESSARY. A SIMPLE MULTIMETER IS ALL YOU NEED!!

The second most asked question that we get is "what do I set my multimeter to?" If you're using the test points as shown in the video then you are measuring millivolts. Millivolts can only be measured when the multimeter is set to DC volts and we recommend a 200 millivolt scale.

This video is of a Hotrod Deville which has a little higher plate voltage than the Deluxe but the bias recommendations at the test points are just fine for both the Deville and the Deluxe. If you're after maximum headroom then set the bias to about 70mv. If you're after an earlier breakup you can go as high as 90mv. Remember there is no right, wrong or "perfect" bias setting within this range. It's where YOU like it best. We simply want you to have the knowledge to be in control of your tone! Try different settings to see what works best for you.

A word of caution!!! Other brands of 6L6's like the chinese tad tubes and sovtek, Svetlana, EH, and the new tung-sol tubes are ALL sovtek tubes and cannot dissipate as much power as the JJ's so I don't recommend running these any hotter than about 75 to 80 and the gt 6L6ge should not be set higher than 70 or you will burn them up VERY quickly!

These amps vary so not all of them will be able to hit 90mv at the test points. If you ask us for power tubes with good headroom we will send a more moderate grade and sometimes these will top out at 75 to 80mv but if its headroom you're after then that is a good place to bias the amp.

The JJ 6V6S's can be biased as high as 45mv at the test points in Blues Deluxe's but most of these amps will only hit about 30mv but even at this setting they sound great. If you want to really push them then you need to drop the value of the final bias resister down by about 20%. A bias setting between 30 to 45 is best for the JJ 6V6S's.
