Default Hifonics BX1605D repaire

Hey guys,
bought this amp blown for 50 bucks. got one or two bad fets on the PSU stage, and the LPF cap on the output fell off...
Mosfets are FQP65N06 and cap is 22uF 250V BiPolar cap.

I cant find the cap specs anywhere online. was wondering if someone can forward me to a place that holds this type of cap and fets. want to get this thing fixed ASAP

Thanks,
David

The caps are very difficult to find. I generally use two 10uF@250v mylar caps in parallel.

cant i take two regular caps for instance, two 47uf 250v caps, connect the negatives together, to end up with a total or 23uf capacitance@250v? or would they need to bee 500V each to end up a total of 250 since they are in series?

The 250v would be OK.

THESE are the caps use.

okay, and do you have any recommended substitutes on the fets? i got IRFZ44n's but was told that they would not be good enough. i cant seem to order the FQP65N06 off digikey.

Thanks,
David

Did you click the link provided?

If you can't find anyone that will ship to your location, the IRF3205 should be readily available. I've used them in these amps before.

i checked out all the links on that page, most places dont have them in stock, nor at a good price. that ST mosfet aint in stock either. what would be better off? IRF305 or IRFZ48N?

Arrow has more than 650 in stock.

I'd use the 3205s over the Z48s in this amp.
