K1803 Pre Amp? in 2 questions + one bonus

Hello or should i say Vello man :wink:

  1. I got confused here, When i read the other messages. Is k1803 a universal pre-amp? cos i was thinking to build an amplifier with pre amplifier. Have i chose the wrong model?

  2. I cant figure this with the power supply. Velleman recommend 1120007M + K1823, should i have it for each pre amp?

Bonus Q; Which amplifier do you recommend to use to k1803, and then i want to chose a power supply how works with all the circuits is there one you can recommend?
:question:
Tnx Indus123

Please let us know what you would like to do with your amplifier.
Supply as many details as possible. The more details you supply, the better we can assist you with your choice of amplifier.

oh, sorry i didĀ“t now.
The primary function is that should be a stereo amplifier to support two speakers aprox 70- 100 w from a cd and pc. but is should be simple, cos i want to follow the process and understanding behind it. The more advance is later. Is this the answer you wanted? otherwise i donā€™t now what you mean.

In this case, your source is a line source, so you do not need a pre-amp.
You can use e.g. K8060 or VM100 (assembled version).

ok tnx for the tips. So if i understand this correct, k8060 is a discreet mono-amplifier, for i.e. the speaker, cos the size? And if i want to built it(them)( cos they are mono? )in a ā€œboxā€, you recommend witch of the to transformer? What the big different between them ( i tried to read it to me but it didnĀ“t say me so much), the most important is that primary voltage is 230/50 for me.

Maybe you have some good amplifier book to recommend?

very great full meā€¦

Weā€™d recommend TR8040 for improved reliability.
Sorry, no books.
