Default 2 Kw?

Will it the mono-blocks run in bridged mono? Have you thought about how much power you might be able to drive into a 2-ohm sub?

Itís quite a nice amplifier youíve built there. Light years cosmetically and power wise from the Leach low TIM-3's I helped a friend build for PA use way back when.

BTW, we blew out half our output transistors and a bunch of JBL 2" compression drivers the night before the first gig. I hope you can let yours warm up and proof it in better than we did.

Thanks MattCatt,

You may hear it on Friday night, I will be in the Rotunda in Kingswood doing a 18th birthday disco!!
I've removed the link to my website for the moment as there is nothing of interest and its a right mess.

Thanks for the comments Da5id4Vz, it will be put on test Friday morning for most of the day (it has already been tested but it needs a burn in). The smaller amp can run mono if the larger one fails so I do have abit of a backup.
The amp is current limited to 16Amps so it will not really run into a 2Ohm load, its been tested to 750Watts into 4Ohm so far. I think if I bridged this amp I would destroy my subs in no time.

I suppose you built the subs too...

Whether you did or not, people on this site just donít stop impressing me. Thatís more great looking equipment. What do you use for the mid/hf?

Thanks again, I don't have a picture of the finished Tops but this should give you an idea, they are now finished the same as the subs with top-hats and mounting poles:
They contain a motorola compression driver and a Eminence Bata12. Crossed over with the subs at 310Hz. I am setting the whole setup up in the garden on Friday so will post a pic of the entire rig then.
