designing basics and 36watts

[fredy]

hi all. I have been reading up on how amps work and how to design amps etc and i have found some great sites and had alot of help from people. however i am still strgling. The maths goes right over my head.

COuld some be so kind to give me the BASICS of amp design to get me started with as little maths as possible (I know the basic electronics maths such as ohms law etc)

also, i am in need of a cheap combo amp. Is it possible to build 36watt for less than £400 $800? And could you point me to a TMB scematic which can be switched down to 18w. i couldn't find one in the download section.

thanks very much!

I buillt a 36er for $70, but I already had a donor amp for the expensive parts- but you can get a crate classic 30 for $250, and make it into a nice amp.

hmmm, i could get [arts from old valve radios but i doubt i will see one with powerful enough trannys.
i was also thinking about making a pocket valve amp using bits i have lying around. i have an onld cd player which will have some spare transformers in it somewhere im sure. Could i use other types of transformers such as the ones found in desk lights and wallwarts? i am assuming they would have the qrong windings and taps but i haven't a clue to be honest.

i just cracked open my cd player and it has a power tansformer but it has nothing on it except a serial code. Is there anyway of finding out the value of each tap? and seeing as it came from a transistor amp, will it work for a push push valve amp?
