smoking hcca 250r, what to do?

[traksta15 10+ year member]

I recently purchased an 250r and today when I went to hook it up, the fuses (2 x 30) blew, so I replaced the fuses and hooked it up again, except this time the fuses popped and smoke came out. Im pretty sure it's a paper weight now but what would cause the amp to do it? I hooked my 1200d back up and it works fine. Im at a loss.

p.s. my elec consists of stock alt, yellowtop under hood, 0ga wire to a distro block, split off into 2 runs of 4 ga (1 run per amp)

If I had to guess, your power supply is probably toast along with some of the power supply capacitors. It is likely that something was grounding out internally since the fuses blew upon hook up.

$100-$200 most likely

This just happened to a buddy of mines 250r. His was most likely due to voltage drop from messing with the gain after I set it.

Repair is probably in the 100- 150 range, or at least that is what he was quoted.

damm. Well I guess $100-200 is better than no amp at all.

If it is for anything beyond a simple repair I go to dB-r!

Caps, resistors, diodes, and FETs are easy for me to change. OTOH, you can't pay me enough to to rebuild and rewind a torrid. Plus, many times resistors are burnt beyond me being able to read the values off of them so they have to go to someone who has access to schematics for repair //content.invisioncic.com/y282845/emoticons/frown.gif.a3531fa0534503350665a1e957861287.gif

I've used dB-r with great results. The only downside is he is usually pretty busy!

Output fets are shorted, your power supply still works is usually the case if it's eating fuses.
