rf power t1500.1bd schematics?

[frankyman]

anybody got some schematics on the output section? just blown half the output but can't find the driver (as i guess they are blown too ) PCB says copyrighted 2007...

You can check with Rockford but the last time I did, they had not yet released it. The attached one should be close enough to be of some use.

They release it already,I can email it to you.

I will also be working on one of these tomorrow.

"perry" I already have the schematics for the older ones, they used the pzta06, 56 pair for drivers, but the new ones uses smaller transistors.



"ian33" that would be great if you could frankholstad@yahoo.no

 

[Perry Babin]

I misread. I don't know what a T1500.1bd is. The T1500-1bd uses the PZTA06 drivers like the diagram I posted.

 

[frankyman]

it looks like it is mmbt5087 and mmbt4401

 

[frankyman]

anybody please e-mail me the schematics? at frankholstad@yahoo.no

 

[Perry Babin]

If Rockford has released it, you can email their tech support to get it.

Also to you perry

thx a lot Ian. but my problem is still not solved . i,m sure they dont are the pzta56 pzta06. the markings on the transistors says 1AM and the other is W2A...not sure what they real name is

 

[Perry Babin]

What's the circuit board designation for the transistors in question?

Do they look original or do they look like they may have been replaced?

Could be MMBT3904 and PMBT3906. The W could be a production code.

Amp I have in the shop has mmbt3904/3906

What's the part number on the output FETs in your amp?

 

[frankyman]

standard IRFP3415 ....if you are sure its the 3904/3906? i,ll get ahead and order a couple
