first integrated amp

Dimitree · 12:45 PM

hi everyone
I'm new here

my name is Dimitri, and I'd like to build a simple, little and possibly "cheap" tube integrated amp.
I have experience with electronics, but not on HIFI, I use to build guitar effects and amps. At home I have several amps like Audio Tekne, Audio Note, Quad 2, and some other, but I want to build a small one for my self (since those are used mostly by my father). I don't need much power and since I'd like to keep the enclosure small (and the costs too), I prefer a integrated one so that I can use just 1 power trasformer and 1 psu circuit. I don't need phono input, just a line input

any suggestions about what circuit to go?

thanks and sorry for my bad english
Dimitri

Here are a couple of links to look at. Look for the "el cheapo." It's supposed to be a decent and affordable amp. Another option is to look for older console tube stereos that are being thrown away or sold cheaply. I found an old Packard Bell for $25 (US), pulled the amp, and rebuilt it. It turned out to be a decent little amp.

Google for RH84 by Alex kitic. Sounds great with Russian el84/6p14p and any NOS 12AT7. And it's low cost.

thanks guys
RH84 looks quite easy for me. can I plug the line out from pc directly to RH84 input? is the ECC81 the actual preamp stage?
