Hello everyone, how are you?
Well, I have this amp, you have brought me, without one of the AB driver cards, namely that corresponding to channel 3.
I wanted to know if anyone here has any of these cards, which are compatible with this amplifier.
I would buy, and I would pay all costs (value of the card, and shipping to Spain)
Thanks and regards.

Have you tried buying it directly from Rockford?
PM seankane to see if he can help if Rockford cannot help.

I will try to obtain it from Rockford ....
Yes, Perry, I would have sent Seankane two private messages, but he does not answer me ..., I do not know, seems to be missing ....

Sorry have been super busy with work.....the a/b driver cards are in short supply at Rockford. I have good used ones but I am holding onto them for now. The facility that made the cards was hit by a tsunami and destroyed. I don't think they are going to re-tool and make anymore. They are releasing a new line soon. I will get as many as I can when they are available and keep you posted.
Sorry for the inconvenience, Sean, work comes first.
Okay, thanks, I will wait the news, and when you know something, I do know.
Thank you very much and best regards.

ROCKFORD answered me, and said that cost me $ 32 with shipping, but I guess that will be shipping to the U.S., I answered them, and asked them to tell me how much is shipping to Spain, but they have not answered me .. .., have given me a phone number, but my English is very short, and I do not think I would defend well, talking on the phone ...
Does anyone around here, could please buy the card rockford in my place, and send it to me to me to Spain? I would pay all expenses, paypal, and I would be eternally grateful ...

Well, I've got an AB card, a P400-4, which is exactly like the other.
I have reviewed all its components (before installation) and appear in good condition.
When connecting the amplifier, there is a constant flashing of protection, accompanied somewhat less rapid flashing power LED.
I have reviewed several components, without apparent results, I can suspect some electrolytic capacitor, but not sure ... any ideas?

Do you have a pulsing of excessive current or a pulsing of DC on the channel where you just installed the board?
Are you 100% sure that the board was working in the other amp?

It is a high current pulse, none of the four audio outputs, has power.
No, Perry, I'm not sure the AB card worked in another amp ....(the P400-4, I had damage to the power supply...)

I was referring to when I measure the output voltage on all audio outputs of the four channels, all are between 0,030 and 0,042 volts.
OK. That's voltage, not 'power'.
If you let is pulse repeatedly, do any of the output transistors begin to heat up?

I had connected the amplifier for 10 minutes, and has not warmed anything, it seems, that no voltage rail.
Well, let's see,,
I forgot to say that this amp, and had been manipulated by someone, I think, a little nervous ...
The AB Channel 2 card also had signs of having been extracted, I took out (to check it) and I saw that several of the holes corresponding to the card on the motherboard, shorted tracks were broken and I did all the reconstruction work, (uniting all tracks messed with thin wires) and then when I plugged the amplifier to test all channels, they offered a low, distorted sound, while blinking the LED protection, but and, in the last test, all channels offer no sound ....
Which leads me to believe that there may be damage to the protective circuit, corresponding to the power supply ....

It's the same as always, Rockford still publishes these schemes, it says that these amps are still in production.
Anyway, I managed to run all three channels, but still no A/B card ....
Do you know anything about it, Seankane?

Rockford provides schematic diagrams for virtually every amp that they've ever sold. If you fault them for not providing the latest models, what do you say about virtually every other manufacturer (other than the Japanese) for never providing ANY tech support?
I do not blame Rockford, not schemes offer the latest models, on the contrary, they are entitled, in my opinion they do the right thing, to preserve some privacy of their industry.
What happens, is that for many repairers audio equipment for automobiles, would like to have in his possession such schemes in your files or on your computer in order to facilitate the task of repairs, thus saving time and labor.
For me ROCKFORD is the world best in amplifiers and woofers for cars that has always existed, how could I say anything against him? never
What other manufacturers do not offer schemes of their equipment to the public, seems to me very bad, terrible, in my opinion, they believe that doing so will have more sales, and forced the end user to purchase new appliances, unable to repair the old team for lack of schema and data.
And nothing is further from reality, because if I am a user, I change my brand, and if it costs me more money the new brand I choose, I will be more satisfied with myself.
Until recently, here in Europe, some brands of computers and electronics, yet still publishing their equipment schemes
I record some German brand, schemes still leave your electronics.
Sorry for writing has been lengthy, but it's what I think,,,
