    Archon 50 with 8 ohm Speaker

    I checked with PRS and you are correct. They said "If you changed the internal speaker to an 8ohm speaker you would want to switch to the 8ohm setting." These are such great amps! I don't know why anyone would buy anything else!

    Archon 50 with 8 ohm Speaker

    The back of the amp says "internal speaker 16 ohms." I guess that means it shipped with a 16 ohm, not it has to have one.

    Archon 25 Plum speaker swap!

    Has anyone tried the Celestion G12 65 Heritage? I searched for the most expensive PRS amp I could find and asked what speaker it ships with. And the answer was two G12 65's.

    Archon 50 with 8 ohm Speaker

    Does anyone know if I can use an 8 ohm speaker in my Archon 50, if I change the impedance selector to 8 ohm? In other words, does the selector work on the internal speaker? (I.e when there is no extension cab) Will the Archon work with any speaker, as long as you set the corresponding...

    Tube Bias Help

    I figured it out. Looks like 400 volts. According to my Groove Tubes bias kit manual, that means 20-50 mV is the range, with a nominal set point of 37.5 mA for El34's. 6l6's are 25 to 60, with a set point of 45 mA. If PRS recommends 30 mA for 6l6's, their recommendation for El34's must be...

    Yes. The Mullard is a long plate made by Sovtek, just like the LPS.

    Tube Bias Help

    Does anyone know what the plate voltage is for an Archon 50? I'm installing El34's. Does anyone know the recommended bias point for El34's?

    How to tame the ARCHON 25 COMBO? WHOA NELLY!!!!!!!!

    Thank you! I don't have a Sovtek LPS. I have a Mullard (Sovtek) long plate 12ax7 so I tried that. Big improvement!!!

    EL34 vs. 6L6GC vs. KT77 vs. 6CA7

    TAD EL34BSTR's will also give you more bass. I've had Groove Tube EL34M's in my Archon for a while. After trying a few different types, I thought they had the best high gain tone. I also ordered some Tung Sol El34's. Can't wait to give them a try....

    How to tame the ARCHON 25 COMBO? WHOA NELLY!!!!!!!!

    I tried a 12AT7 for the phase inverter and that worked well. I"ve also thought about a 5751 for one of the gain channel tubes, but there are three of them and I have no idea which one would work best....

    Archon preamp tube layout chart?

    I think you are right. The Archon preamp tubes are all 12ax7's. But I tried a long plate 12at7 for the phase inverter and really like the effect. The distortion is smoother than with the ECC83 that was in there. I like JJ ECC83's for all the other positions though....

    Archon preamp tube layout chart?

    Quick question. Are all the preamp tubes in the Archon 12ax7's? I'm not sure if the phase inverter, for example, should be a 12at7....

    Archon 25 Plum speaker swap!

    I have a G12k-100 in my Archon 50. Sound much bigger with that speaker in there. Smoother highs; bigger bottom.
