Orion 2250sx opamps ?

Clipped · 18th October 2007, 11:13 AM

in my never ending quest to burn more cash... i may pick up a couple of 2250sx amps... but i seem to recall that there are a couple of opamps that are not standard numbers and may be hard to find?

also does the 2250sx have those fat diodes on the back of the board like the 2150sx? because these diodes are hard for me to find and may be the deciding factor in whether or not i get these amps.

opamps?
diodes on back?

if i get these two amps, i'll have

2 x 2250s for subs
3 x 2150sx for midbass
2 x 225 hcca for mid/ hi's

Muahahahahahaha !!!

thanx

In the photos I have...

I can't see any rectifiers so it probably does use the large rectifiers mounted under the board.

NE5532 and NE5534 are the only op-amps used in the audio section.

ahhh so the opamps i saw in one of the amps, has been replaced to some funky korean number...

which probably means the mpsu57/07 was probably misdiagnosed as the opamps being faulty...

thanx!

These are the original op-amps in this 2250 (see attached). The 2 not shown are also NE5532s.
