Okay I've install the new output transistors ready for the next steps not sure how to test the idle and ready to learn on this please school me on it! Also ready to the adjust the bias for the new outputs.. I cant thank you for all you have done it has been awesome feeling to be able to learn all th...

Thanks for the visual location I would have never looked under the black spacer lol. So by using the meter all of those predrivers and drivers are matching in numbers on all the other channels so I'm sure they are 100% good :D I'm going to order the new output transistors tonight. I will follow up o...

Okay I found all but 217 maybe its just late but anyways Ill look at it tomorrow after work I'm hoping to have everything needed to order on Friday... Since you said replacing the other two output transistors which I agree on the other channel how do I know which is which? Also we can get to the idl...

Thank you, I wasn't expecting that and that's when I spend more time testing on each one to make sure I wasn't doing something wrong haha.. and yeah I'm going to order for each since that makes sense to do that. I will go thru and continue to check each resistors as far as checking the predrivers an...

So an update found two output transistors was not showing the same as the others so I removed them and boom its staying in the power on mode and not switching back and fourth.. wow I'm so grateful for all you help in getting this old school working. I still need to get the replacements on these to f...

Its the rear right channel and ill look at that right now thanks a million

So how would I check this out? can you help me explain what I need to do? plz plz

Good Day trickyricky.. Okay so check for DC voltage on the speaker output terminal front left and right are low .002 or close to that it jumps around but nothing high and the same with the rest except back right side jumps from 1.0 to 3.2 DC Volts so I would assume that this is where the issue is ca...

Rail caps are not bad then took the cover and none look damaged and if you could point me in the right area as what to check and how to check them please

So update on this is I checked fused on internal amp on meter said was good. I replaced the four large capacitors near the toroid/transformer and still no luck. :( I'm going to order the next four capacitors under the crossover/RCA board but I'm running out of steps trickyricky... Please help!!!! I ...

Been running two 12 subs at bridge... I removed all connections to verify if it was a speaker issue and no luck on getting it to run Constant on power green only! So I order the replacement caps and I hope I ordered the right ones I saw a link from Erick http://www.soundbuggy.com/Eric/Car%20Audio/le...

Okay I'll look into these and try and replace these caps! I hope these are the reason and will post back when replaced if anyone could help try and chime on to why it would switch from OVL red to power green on and off constantly that would be awesome thank you

So any help would be appreciated I have this ZX450 ver.2 white case not sure what happen but driving home from fireworks and the amp just cut out and I was not playing the stereo loud or anything but the next morning I noticed that the lights on the front was switching between red (ovl) and green (p...
