Thanks for the reply. However, as i dont have much knowledge, i need to ask the following questions again:

1. Whether the chip amp TDA7293 be ok to drive the amp? I am not using it for public performance. It will be basically for use indoor.
2. Will i need to put a crossover network after the power amp to  divide between the woofer and the tweeter.

@JM Fahey...So sorry that he died, i was looking forward to some of the projects that he said will be posted.

I am decided on the Kreuzer Pre-Amp looks simple enough and the parts are available. And, best for me, the PCB design is there.

I have seen the TDA7293 based Randell Amp in http://www.ssguitar.com/index.php?topic=2324.0. What do you say to the above preamp driving this amp. Again, the simplicity and readymade PCD is a boon for me.

Also, i finally get the Eminence BETA 12A  :dbtu: After checking out some bass amp design, do you think i'll need a HF driver/tweeter too. If needed, I can get them from here http://ahujaradios.com/productcategory.asp?id=7&sc_id=49

@ polo16mi ....I've check it. Let me see if i can fabricate the PCB myself. Otherwise i might have to go for a simpler one.

@ J M Fahey...Thanks for the info. I've called her up and ask her to get the Beta 10A, seems it is the same price and weight/size as the Legend.


What do you say to the Pre-Amp listed and connecting it with the Rod Elliot Amp. I have found this website. Seem to be quite easy to use.

I've been lurking around in this forum for quite sometime. I find that, comparing to other forums, a sense of family is there. I've find that very interesting. That's why i'm interested in joining here. Sounds corny, but that's the truth.

I am planning to build a bass guitar amp and i find that there is a dearth of specific plans that i can use (maybe i did not see the obvious one). The funny part is i have to build my amp around the speaker that I'm getting. I live in the northeastern part of India (near Myanmar) and it is very difficult to source quality speaker. Luckily, my cousin is bringing me an Eminence LEGEND B810 from Canada ( it seems its the smallest she can find around her area to fit in her luggage). So, all the design has to revolve around this particular speaker. So, i have the following questions:

1. What wattage of amp will be suitable to drive it?  The amp will be mostly used for home/indoor application.
2. What components will you suggest - chip amp or solid state?
3. Can the Rod Elliot Project 27 be used or any other design? (I don't have any knowledge of circuit design and i have to build my amp based on ready-made design)
4. So far, the only amps that i have build are based on LM 386, TDA2030, LM1875 and a simple transistor amp using 2N3055. So, i cannot  attempt complicated design.

Thanks,
Rips
