Class aDo you mean pure Class A or Class A/B amplifiers?
Yes.. I would like to go pre assembled way.. But any idea where I can get pre-assembled class a kitsIf you are new don't go for a DIY way assembling all the components on PCB by yourself, changes of wrong placement and dry solder are higher. Get yourself a pre assembled kit. Secondly I will not recommend Class A Amp for a beginner. I will recommend you to go for a low power class AB or Chip based amp first.

Have no idea how to do it.
True. The challenge with class A is not the soldering. It is the chassis and wiring, and to some extent the biasing process if one isn't familiar with it.Class A is very challenging from mechanical point of view. Large heat sink for dissipating the heat automatically makes the cabinet large, huge capacitor bank raises cost of parts substantially, etc..
Hi,
I have some PCB's to spare of stereo Class AB amplifier. power output is 70+70 W into 8 ohms and 120 + 120W into 4 ohms, SNR > 109dB, THD < 0.01% at rated power. it has power supply and protection circuit inbuilt. no wiring hassles so, would be easy for you to have a working amp as you would need only power transformer, enclosure and in out connectors in addition.

Are these populated boards... what is the power supply needed?
Great!
Would like to build one stereo amp for my bookshelf spkrs...
Can you pl let me know the cost of the kit.
Regards
Hi,
complete kit excluding heat sink will be around 5~5.5k

Thank uHere's the pic of the module
Still this kit is available...?Hi,
