Hi all. . . I have been away from this forum for a while. I considered making an amp about year or two ago but gave up. I am deinately thinking about it again. Here is what i am thinking. I want a very portable power amp (I am in college) which I could use to power my Zoom g7.1ut or my laptop or any other form of music. The main purpose of this amp though would be to power my zoom (guitar mfx pedal). I figure it can be used as a pre-amp because it has preamp sims in it. So far what i am thining is making a 15watt stereo amplifier powering 2 8 inch speakers. Here is my list so far:
amp:

and have it power 2 of these speakers

Correct me if I am wrong but I think this transformer will work.

Somthing like this to put the amp in (its rather expensive in my opinion i am sure there are better options)

I have no idea what type of power supply I would need to get so if any one can find a decent one please tell me.

I know there are a lot of misc parts to get like input jacks and volume pots and so on, but am I missing any major parts? Also would this set up work? please steer me in the right direction. Thanks

Hi all. I own a marshall VS 30. I have a zoom g7.1ut and i want to use it with this amp. My question is, is there a way that i can bypass the pre-amp in the marshal and use my zoom as the preamp? Basically use my amp as a power amp. Any help is appreciated .

Somthing just came to mind. What exactly would stop me from using batteries. They are a lot cheaper than power supplies (i also have some rc ones) and i dont mind wating for charging. would this work. because i could u 3 7.2v 2300mah battery packs in series giving me 21.6v. THe conrad website rates the amp as 6v-20v. would ne of this work.thanx

I have one last question. Will a computer power supply work for an amp because i have a couple pretty good ones not being used. Thanks again for all the help.

Yes conrad is rather close to me and itwould be nice if i could find most everything there.

Yes it is the black module. Would there happen to be ne decent speakers in conrad? thanks for the help.

Hi thanks for the info. I have found an 18 watt amplifier cuircuit on conrad already built for only 15. now how much would it cost for a 8 inch speaker. I am not looking for top of the line but decent one. I can raise my budget because that seems needed. and are there any specs i should know about power supplies. I am kinda considering using 2 of these amplifiers connected to 2 speakers and using the stereo mode on my pedal. Kinda making a 2x8 combo. Would this work. Thanx

I am an absolute noob at building amps. I am looking to make a 30-50 watt combo amp. I have no clue where to start. also would i be able to do this for less than 80 euros? Is there any tutorial  or somthing that will show me exactly how to make one ( i am kinda worried about blowing somthing up). I have a digitech rp 80 so i imagine i can use that as a preamp. I also live in austria if that effects anything. Any help is appriciated. thanx
