Well, 6L6GC / 6L6 / 6L6RAPMASTERHIPHOP or whatever are all the same nowadays. I think 6L6GC's were a version of the 6L6 that could take higher plate voltage originally. The "S" part in GT-6L6-S is just a model name, not a tube type (Like the JJ ECC803S / ECC83S, even though it doesn't say ECC83 it actually is an ECC83, they just added an "S" and a "0" )

1 JJ EC803's/High-Gain 12ax7 with Balanced Triodes (for phase inverter slot)
1 JJ EC803's/High-Gain 12ax7 with Low Noise and Microphonics (for tube closest to input jack)

Bias the 6L6's to 45mA?
Bias the ECC803's to _____?

I think I want a loose sound because I played a Peavey XXX and really liked it with the loose knob on! On tight and middle it did not sound as good to me.

You don't "bias" preamp tubes yourself, the bias on these is fixed and is a large factor in how the amp sounds. You just pop them in. The bias on the 6L6's have to be determined by plate voltage and maximum ratings, i.e. if plate voltage is 450 volts and max dispassion is 30w, and you wanted the bias set to 70% of max dispassion (21 watts) you would set the bias to roughly 46mA (Disspassion / Plate voltage = 21W / 450V = 0,046 amperes).

Taken from thegearpage.com.

The main point is, if the amp is designed for 6L6's, thats what you should use.

Thanks for that info Jopop. Have you played the JJ ECC803S? Do you think it's worth the extra few bucks over the JJ ECC83S? I guess I want a sound similar to the Peavey XXX.

I have not tried that tube. Read what this guy says:
http://eurotubes.com/euro-e.htm

From what he says, the "regular" ECC83S would be your best bet.
He's really good on JJ tubes, too. Best prices you'll find i guess.

Edit: Check out https://ssl.eurotubes.com/cart/inde..._category_id=87

- You want the "Crate Red or Blue Voodoo120 High Gain Retube Kit with 6L6GC's"

Thanks man, didn't realize his prices were that low and he had a kit.

Now, since my amp is not here with me, I don't know if it's like the Marshall that Bob biases in the video on his site. Do Blue Voodoo 120w amps have a trim pot? Can I adjust the bias like the Marshalls or do I need to put a trim pot in place of the simple resistor? If I have to do that is there a writeup on the web? I will buy a bias probe and I already have a multimeter. Thanks

I own the exact model, and I highly reccomend Sovtek KT66s. You will have to take off the tube retainers, but other than that they sound great, and have low microphonic noise too.

From the tubedepot website..
"The new JJ/Tesla ECC803s is a hi-gain 12AX7 that has a spiral wound filament to reduce noise and hum. The construction is different from the JJ ECC83 in that the plates are more conventional, but have a special heat dissipating fin that serves to improve efficiency and gain. If you want that great JJ tone in a hi-gain package, then these are for you."

Also, on the tube depot website when u order tubes you have the options of high-gain, matching, balanced triodes, matched and balanced triodes, low noise and microphonics.. all for extra money. Should I order any of these options? I think I'm gonna get tubes from tubedepot rather than from the local amp guy because I know for sure they will be JJ's and they cost less.

The ECC83's have more gain (have these in my amp)than the ECC803's
