Bugera T5 Infinium Bright Cap Mod 220pf on Volume and Gain center lugs

I’ve had this head for awhile but sound too muddy with humbuckers even when treble dimed. This mod should tame the lows a bit. Adding 220pf in serial to gain and volume knobs. Also using Tungsol preamp and Mullard EL84 power tube and Jensen 8″ in custom made cab.

Removed 5 or 6 screws from pcb and knob nuts and back panel to disassemble. Always use a discharging resistor on caps and ground to chasis so I don’t get shocked.

What I learned from using this head is that attenuator kills off highs when used at 1 watt or .1 watt. Using on 5 watts is the brightest. I actually went back to using the mullard preamp tube instead of the tungsol. Mullard has a little more gain and more bass but on runs good on the full 5 watts. I don’t think I need further tweaks, its sounds really good now on 5 watt full power with neck and bridge pickups. I also ordered a Tung Sol el84 power tube, supposedly the best for Vox tones, which I love.

Edit Tung Sol EL84 just came, Chimey like a mothafucka, Different Vibe than Mullard in there. Definitely sounds more like a Vox pairs nicely with the high gain Mullard preamp. Money well spent.

Todo, add a dpdt switch for both Gain and Volume cap mods. Seems a tad bright on 5W mode but good on 1W mode attenuation setting.
