Question Opinions Required

Hi, I've been reading the forums for a while trying to get back into some construction but due to a lack of free time I've decided to consider an amp module to save and time and cost for a Sonotube project.

This is the module I've been looking at that was recomended by another member. The module seems very good value for money that will require a small amount of work to give me a working amp.

http://www.profusionplc.com/cgi-bin/...tno=ECF20-DEMO

Does anyone have any experience with these modules?

Can ony one recomend an alternative?

I sould say the the amp will be driving a Volt RV3863 driver which will take about 400watts and is an 8 ohm load.

I would consider a kit etc.

Thanks m0cea

Thank for the reply.

I was looking to get an amp closer to the 400watts into an 8ohm load to be honest.
Thought the site was interesting and will keep it in mine for future projects.

No good for a sub though or at least not unless your power requirements are modest and/or your using very high efficiency woofers such as PHL's etc.

Mark,

If you go with the LT I discussed in my email, you'll need quite a bit more than 80w for healthy listening levels.

Also Mark,

If it were my money, go with the Exicon TO3 amp.

Actually its probably too good to use just for a sub but then again the Volt R3862 is a bit special itself.

Use an LT with these and you'll wipe the floor clean for quality and depth...

...or your money back

EDIT: I meant the Volt R3863 but you get what I mean

To simplify:

Use opamp (OPA604) to feed bias network at node between CR2, CR3. Add 3K3 1/2W pull-up resistor to the anode of CR1 to +24V and 3K3 1/2W pull-down resistor to the cathode of CR4 to -24V.

Use Exicon outputs, note that the case is grounded so no insulators required.

Use 60-0-60 500VA~800VA transformer for 400W/8R
