Pc2350

I'm working on a ppi PC2350.. Can I swap out the 70n06's for 3205's? do i need to change gate resistors?

I don't know enough about what the driver ICs can withstand so I'd suggest using the originals. Long term reliability may be an issue with the 3205s.

The gate resistors are 22 ohms and won't be a problem.

The driver ICs have almost certainly failed. Order replacements.

Alright Perry.. its a shame I have 200 3205's sitting right next to me.. All the Ic's are already on order.. I have to post a picture of this amp.. it has some sort of mod done to it and I have no idea what it is supposed to do...

Perry didnt want to waist the board space to start another thread.. I have a buddy that is/was running a 2350 in his car.. He smoked it about two weeks ago and I told him I didnt have time to fix it yet.. Well he wanted to try it himself ( a person with little to no electronics expereiance what so ever) I told him not to and I told him what to buy and to have it ready for me in two weeks ( i figured by then I'd have some time ). Well I told him to bring it to me today... He brought it alright.. He took the transformer out and completely unwrapped it! (he thought he was doing me a favor I guess) I called him and asked what the F*** had he done... he replyed It looked burnt so i took it out for you to fix and i unwrapped it because I thought it would be easyer to fix!........

My question is Perry.. What can I do? I'm pretty sure I can wind a new one.. but were do I start? I know about the primary and secondary parts but from looking at my burnt 2350 there is another wrap with 4 smaller wires.. Can you help me?

You're lucky that you'll have yours to use as a guide.

You'll have to match yours to rewind his. When you unwind yours, I'd suggest that you either take photos of it (at least 20) as you unwind it. If you have a video camera, that would be better. Have someone capture the entire process as you 'slowly' unwind it. You'll need to lay down the new windings as close as possible to the same exact layout as the original windings.

If you have any specific questions, post them.

Damn I was hopeing that I could leave my amp alone.. it has enough issues of its own..but ok..

[Perry Babin]

I must be confusing your amp with another 2350. If your transformer isn't damaged do NOT unwind the transformer.

yes My transformer is perfectly fine..

I've never rewound a transformer....yet, but the 2350's looks like a P.I.T.A.
