Fender Frontman 212R 100W 2x12 Guitar Combo Amplifier - Answered Questions & Fixed issues

Probably a bad transformer? Do you have power on the secondary side? Power in is one thing power out is another, hope this helps?

It does indeed sound like the power amp section. Contact the manufacturers customer service department for the schematic. Then trace it back to the problem. If you do not know how to do this, you're best taking it to a repair shop. If you poke around inside with out knowing what you're doing you can fry something or get a nasty shock.

PRE OUT/PWR IN - (1) Effects Loop - Connect PRE OUT to an effects device input, then connect the effects device output to PWR IN. (2) Multiple Amps - Connect the primary unit's PRE OUT to the auxiliary unit's PWR IN. The primary unit is used to control all auxiliary units. (3) Recording or Reinforcement - Connect PRE OUT to sound equipment's input. Both jacks use a TS (Tip-Sleeve) standard type plug for connections. PRE OUT includes onboard tone shaping.

try plugging into a different socket if that doesnt solve problem you may need to replace cord. sounds like a loose neutral in socket though.

When i turn on my 212R it turns on in drive channel. if footswith is plugged in, then it turns on in the clean channel, but after switching in drive it is impossible to switch it back in clean channel. What could be wrong? Swith position doesnt change anything and it seems like switch is OK.

speaker placement, might have to try some different locations or tilt back a little.

Find another speaker to check it with. I've had several fender amps to blow their speakers during loud playing.

It may be a broken solder joint. It may also be a capacitor in the power supply is failing, but a bit less likely.

Pull the chassis out and look closely for any breaks in the circuit board. If none are found then look at all soldered connections, or better yet- reflow each one.

Power it up outside of the case and if it cuts out again, check for voltages at the finals, You should be close to 48 volts from chassis ground to the high side power rails of the finals. One positive polarity with respect to ground, the other negative. You can measure the voltage at the 2-4700 microfarad filter caps. You should see about 48 volts across each cap. If voltage drops on one side, check the cap visibly for leakage or bulging- replace it if either condition is found..Also check for 16 volts at each of the 50 microfarad caps nearby for the same scenario.

Also clean the controls if that has not been done yet either.and look how they are soldered to the PC board. .

... do you, by any chance, have non humbucking pick ups on your guitar? Just curious...

Fender Frontman... | Answered on Oct 27, 2013 | 857 views

Your amp uses a "reverb tank" that has two or three springs that are suspended. One end of these springs are driven by a transducer and the other end the vibrations are picked off with another transducer. If you dropped the unit, possibly the two cables that go to this tank on the bottom of the cabinet have come loose. other possibilities are the transducers have been damaged... or one of the cables has broken or the electronics that drives this and receives the return has broken. If you are not electronically adept, the only DIY is to check that the cables that plug into the reverb tank at the bottom of the cabinet are connected. The tank is often covered with black cloth like plastic and the cable have RCA type plugs that plug into it.

If the humming ONLY happens when a cable is plugged into the amp, the problem is in the cable or the guitar. Poor quality cables or wrong cables will result in hum. Defective wiring or connectors in the guitar OR having the guitar near a source of magnetic fields will result in hum. We cannot diagnose these possibilities remotely.

You should be able to SAFELY IF both the mixer and the Fender are powered from the same receptacle or power conditioning module. Keep the cable short <10 feet OR convert to balanced lines for long runs and then of course run power alongside the run so the units are powered from the same receptacle.

yes,, Pre means before powered or amplified ,, so yes you can do this to a powered mixer, just be sure that the power is off before making any connections,, without the ground of the rca cable touching , the blast to the speakers can invert the cone !!

There is something resonating with that note frquency. Often the grille or wiring inside will rattle at certain frequencies. You need a sustained source of these frequencies to find what is causing the noise.

Numbers on volume controls mean very little as there are too many things that affect the level. If you are really driving it hard you may be causing the amp to go into thermal limiting. This is a 100 watt amp so there is a limit. The sound level from it probably can easily exceed legal limits. You should get and use a sound meter. If the amp can create 100 Db that is all you need. If you stay in that environment over a few hours, you are a candidate for hearing aids in the future. I know several musicians that are in this condition and now are wrecked. Remember that loud does not equate to QUALITY... Your group should have a sound level meter and with that you can tell if the amp is performing as it should. One thing to be careful of is high frequency feedback, even that above what you can hear that heats up the amp with frequency output you are not using. Make sure your guitar cannot "Hear" the amp. Also be careful of boosting the high frequencies. Also be careful of large bass pulses that you can see drives the speaker cones to the limit. If the cones move too far, the voice coil leaves the active magnetic area causing excess current and amp heating. Make sure there is free airflow around the amp and especially the heat sinks.

This is likely a failure of the power switch. It momentarily contacts, charges the power supply caps and then breaks the contact. This is not that uncommon as these switches are not well made and often not designed to handle the inrush surge current.

The power amp input jack takes "line level" input BUT is monaural (single channel). The output of an ipod is Stereo. Hence you would have to "mix" the two channels before connecting to the Fender. Mixing does NOT mean just tying the two channels together. A minimu thing would be a passive resistive mixer consisting of a resistor from each of the IPOD channels to the common point going to the input of the Fender. Remember if you plug into the Fender power amp input you DISCONNECT the preamp and other circuits and would ONLY hear the IPOD input.

If you don't want distortion, get rid of the overdrive pedal... Twangy USUALLY comes from the GUITAR and NOT the amp... test it on a different amp to decide... Buzzing CAN be caused by "fret buzz" which is due to IMPROPER guitar setup such as neck bend and string height.
Start using ONLY clean channel on the amp and NO reverb. If you verify that the guitar sounds bad on a different amp, take it in to have it setup properly.

The Fender Stratocaster (in common with all Fender guitars) has passive pick-ups so should be plugged into the no 1 socket.
Whilst it will work in the No 2 input socket this has lower sensitivity and is intended for use with guitars that have active (battery powered) pick-ups.
