Default Orion Hcca5000.1D SPL

The power supply drive section uses A1023 and C1027 drivers which I need to replace and don't have. I do have the 1220/2690 pair and the bd139/140 pair and and abundance of others.

Which would be suitable replacements for these? Normally I would just experiment but seeing as parts for this amp are not cheap I want to reduce my chances of failing.

The 139/140 are the most common drivers used as subs.

So I have a question for you Perry.

In the thread located Sound stream XXX-4000D repair help

You mentioned the power supply failing while the vehicle is being started and remote voltage is being applied.


Is the Orion 5000.1d spl similar in design to which you speak of? If so how can fix this or atleast give me a direction to go in.

This has happened to me twice with this amp and ive been scratching my head for a year on what the heck ive done wrong. You've made me realize that the last two times ive done it i have had my doors open and lights on in the vehicle without the vehicle running and the stereo off and working on something in the vehicle. Go to start the vehicle and the amp starts to draw current when the amp is told to turn on. I am assuming now because the battery voltage was low.

The problem happened when the amp remote was powered by a source that went directly to battery voltage and didn't switch off when the engine was being started. Is that what you had?

What i think may have happened is the engine was still cranking when the remote switched on. The unit switches off when turned over but its like a timed delay when it senses the engine being cranked. Not staying off the entire duration while the engine is being turned over with a weak battery.

That sawooth on pin 5 doesnt look right. Would this indicate the timing capacitor has drifted out of tolerance? The power supply is operating at 20 khz to 21khz seems a tad low.
