J.M., I'll post it if I can get my hands on it. I have a good friend that was the production manager for the amp department at Fender. He's still there in the R&D dep't now. But I hate asking him all the time for information. I am a professional auto mechanic and electrical and air conditioning specialist and hate it when friends always ask for car information. It seems as if they are friends just for that reason, so, I don't want my friend to feel that way too. As to there being a difference, as I recall, there was but that difference may be small and not an issue. I just figured that since this project is going to be handled a few weeks down the road that I would prefer knowing that the working schematic in my posession was absolutly correct. My problem with the 212R is no gain. The volume is moderate but when turned up does not change. It seems to stay at what would be the number 2 level. This is on both channels. Again, I'll post the schematic if I get it.

It's not a new amp, it is actually a Fender warrantee return. The FM and Frontman are different amps. The FM is a cheaper version. The circuitry is different. I have a number of Fender amps and all of my FM series amps are assembled much cheaper. The pots have no nuts holding them to the chassic as they just stay in place from the legs that are soldered to the board. My schematic for the FM 212R does not match my Frontman 212R amp. I was confused by that too but owning a few of each has educated me on that.

Amplifier Discussion / Frontman 212R help needed
May 04, 2009, 08:57:48 PM
Hi everyone. I just purchased a Frontman 212R that has a problem with the gain. The amp is loud enough to hear while practicing but when I turn her up the volume stays as it was. No increase. What I really would like is a schematic for the Frontman 212R. I have the FM 212R but it does not appear ro be the same. Any help on a schematic or where to look would be appreciated.

Okay, Got the proper information from my friend at Fender on this. It could not be any easier. All I needed to do was remove the black/green wire from terminal number P-12 and team it up with the black wire at terminal number P-11. It now plays perfectly. Thanks for the input from here. Bob

Thanks for the schematic. I do have that one. I must be missing something though as the schematic has the transformer I have for 220-240 volts as well as 100 volts. (Same unit just wired differently for the 2 different voltage uses.) The 120 volt portion is a different transformer. I know that the transformer for the 240 is usable with a rerouting of the wires. That is what was done to the Automatic GT I have. I did finally reach my friend at Fender and he gave me this rerouting. Blk/Red P-9.. Blk/Yel P-10.. B;k/Grn P-8.. and Blk P-11. The only thing is..on P-11 is the white wire from the on/off switch.  Thanks again...

Hi all, I just purchased a Fender Stage 160 DSP that is a European model but I live in the good ol' USA. I know that Fender uses a universal transformer for foriegn models that can have the transformer wires repositioned to operate on our voltage rather than the 220 volts that it is set up for in Europe. Does anyone have the positions for the wiring to do this? I have a Fender Automatic that is also a European model and a friend of mine, that works for Fender as the amplifier production manager, got for me and he repositioned those wires to work. Unfortunately, he moved from the Corona office to Scotsdale and I am having a little trouble reaching him. So, you guys are my best hope.
