How to adjust the Bias of a Fender Hot Rod Deluxe 

Cheers mate. Stay safe when you’re doing yours.

@@DogsharkGPS To even be safer get one of those plastic screw drivers to adjust the pot..

Swap yer?

@@DogsharkGPS Mate says No New Lovers!

Already moved it on. Wasn't doing it for me.

Fender recommends about 60mV but i don't know if this parameter works well w/ any tube brand...what do u think ?

To be honest I’m not sure. That’s within general tolerance but on the hot side. Might just be hot tubes.

@@pdx_angler9760 coz I’m not a clever c*nt

Honestly no idea. Probably does in some way. But not enough to warrant adjusting the bias again.

@@DogsharkGPS I just got my hot rod deluxe and hopefully don’t have to adjust too much. Btw you could also switch out your preamp tube so you don’t need that volume fx loop circuit which would be a cleaner setup .

@@DavidsMusicChannel yeah. To be honest I moved the HRD on pretty quickly. Wasn’t getting the tones I wanted. Replaced with a Vox AC15 and very happy with that.

@@DogsharkGPS oh cool. Did you make a review on that too? Will subscribe..

@@DavidsMusicChannel actually did do that yet. Only did this one coz I was messing with the bias. Probably should do tho. Got another MiJ Strat arriving this week so will probably do that too.

Take it to an experienced tech

Not sure about that. As far as I understand biasing on a HRD is more about getting the right balance between clean headroom and where the amp starts to break up. Might be tho. Easy enough its worth doing to find out.

Could be. Can also retube it. I'd recommend Sovtek 6L6GXT+ tubes as they're the correct wattage output (30w, vs 25w on regular 6L6s) and are 'hotter'. Your preamp tubes could be a bit soft (12AX7s) You could bring to a tube guy and have him do the biasing if you're unfamiliar or unequipped. The various voltages up to 430 volts DC (and the 110v/240v AC mains voltage) will tear you up and give you a bad day if you're not trained in the "keep one hand in a pocket" mentality. Side note: the old tube tv's (both tube and 'modern') have heat sinks, etc. inside. Those are never grounded and a mis-placed finger would pump 300-900v AC (or 32,000 volts on the back of the TV tube) across you. Not a good day. ;) Not trying to scare, but make sure the dangers eluded to made known. The secret to high voltage is "keep one hand in your pocket". Not literally, but it means to only use one hand when probing with a multimeter, etc. Touching something with a voltage charge with "one hand in your pocket" will give you one hell of a jolt, but your hand will come off of the charged point. Resting your hand on the chassis and your other hand touches something in the same situation? Goodbye Charlie. Lights out, and save the family cremation costs.

Could be the speaker. According to what I've read the Eminence Swamp Thang (12" 8-ohm 150-watt) is a great replacement, not nearly as dark as the factory speaker.

Thanks for watching
