Hi Romulo, mj21193/21194 available here in my place. The electronics store right accross to the apartment building where I live. I'll be going home next year if you are not in a hurry. I can bring some then pay me when am there. Only am not sure if it is economical to buy hence 5 pcs cost NZ$28. cheers, Al

Bro!kamusta?frankly speaking regarding my knowledge about the attitude of this CROWN XTI amp.the amp supply is not good very fragile just dont make your xti amp on clips it will damage the ic FAN7380 and sure it will damage everything.But the main amp itself is very good and powerful if you set it bias at its normal condition.you can study this amp and its family like CROWN PULSE SERIES,XLS,XTI this amp using the same circuit but this XTI is the upgraded one.best regard!

to sir tony,
i have always following your notes,
always found it so useful,
about amp classes
i see how you always praise the leach amp,wonder why because it is class ab?,or because of the very low noise design,hi fi?and how can you say in another thread(sayang kung gagamitin lang pang sub)and why you say stay away leach with step,does step affect leach clean sound?did i get it right sir?are you suggesting this design is good for systems mids and hi's?
another thing,when nmos say b500 nmos is not good as nmos amp etc,.then you said ''use is as sub amp''what are you suggesting sir, your thoughts are full of wisdom,did i get it right this way?
we can use any powerful amp ignoring sound clean?at any class?for sub.....
then,use clean sound amp like leach for mids and hi's,and stay away fromamp with step?

i built several Tigersuarus amps and the Leach Double Barreled amp and that was the basis for my praising the leach....
at about the same time i was running a electronics repair shop and had a chance to repair and listen to many kinds of japanese amps brought in by ofw workers mostly coming in from the middle east...
the Tigersaurus had a punchy bass but in the mids and highs i found them not listenable for long periods...
to my ears the leach double barreled amps had the best overall sound, i even likened it to sound like a tube amp...so it is a waste to use it for a sub only amp, but that does not prevent you if you want to use it as such....
a sub amp requires a powerfull amp, mosfet type amps are better in that department...
yes, a super leach for the mids and highs is a good idea...

^can you post schematics?
you can start reading these threads to get ideas, you will need higher voltage rated trannies, Vceo should at least be 200v for output at drivers and VAS....
