TA3020 amplifier kit

Da Cristi Ven 18 Feb 2011 - 17:49

Ciao a tutti,

In the past months i had limited access to some websites including this, so i want to take the opportunity to announce that i plan to introduce an amplifier kit for TA3020, and i would like to make the debut here, in this friendly community. I want to listen your opinions about, and to make the design interactive. Some of you will prefer to use tru-hole components, others will want more space for input caps, on-board or separate aux. supplies, etc.
At the end of the design stage i want to organize a group buy, to save cost for shipping, we know that the shipping cost can kill a deal. Recent shipping delays, frustrations, and needs to change the shipping company few times a year makes me decide to pass the distribution to resellers or groups of peoples interested the design.
We can start with a simple design, cost effective, which will allow those who couldn't afford to buy one ready made board yet, and in time we can go for a more complex version.
Waiting for your ideas. Idea

Hello Cristi, Mattheus here Very Happy

thanks for the opportunity to give some ideas and feedback...
from my side i'd like a board with enough room for tweaking and experimenting, so in other words built with discrete (tru-hole) components and with some more space to place input caps of choice.. of course this means perhaps almost doubling the size of the PCB but i think you'll make some people happy including me...
one recomendation (beg Smile

) is to have extra care on self oscillation issues, as some boards need a very careful planned layout to keep things running smooth
thanks and keep up the good work!! Cool

Penso che potrebbe essere un altro prodotto da mettere a listino in un eventuale spaccio aziendale (o attivita commerciale in rete) , così come da idea lanciata su post su audiophonics, spero di aver capito bene la proposta di Cristi TA3020 amplifier kit 196713

You read my mind, Tfan.
I fully second you.

Hi there, so what for those who aren't fine Diyers but want a fine&fully functional ready made 3020? Razz

Hello everyone again.
I manage to login again after one month Please

hopefully won't be problems from now Don't know

Thank you for the proposals received in the meantime, i suggest to continue the work at the project, i attach a schematic, similar with the TA3020v2 which is very popular, and we should discuss based on this schematic. then, i can start designing the pcb then based on your proposals. from the attached schematic i removed the 5V supply and Vnn+10 supply, which can be added later or not included on the amp board, and the voltage provided from external source.
