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.

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

These are some of the other amps I'm considering

hi there,
try these http://www.williamshart.com
the john linsley hood designs are great, these kits are of high quality, i have no connection with this company but know the amps very well especially the jllh 80w and the jlh phono amp
regards
bob

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
