batdan1553552684 Posted October 7, 2009 Share Posted October 7, 2009 I'm looking at building tube pre and power amps, however want to do it in stages as funds allow. If I start with a pre amp can I connect it to my existing receiver (no pre in) on one of its standard inputs ? Link to comment Share on other sites More sharing options...
Shane Hanify Posted October 7, 2009 Share Posted October 7, 2009 Gidday Batdan, you mean as a buffer or do you mean as an output rather than input? If it's an output (and you meant preout rather than in), yes you can - you just go through the tape loop (use the rec out which is usually a set volume). Cheers, Shane.

batdan1553552684 Posted October 7, 2009 Author Share Posted October 7, 2009 As a buffer I think ?? What I would do is connect the sources (CD initially) to a preamp I build, and then connect the preamp to my integrated amp which has the speakers connected. This would be a temporary measure until I decide on power amps. Cheers Link to comment Share on other sites More sharing options...
tanman_sg Posted October 7, 2009 Share Posted October 7, 2009 If your integrated amp has links between pre-out and pre-in which you can remove (so that you can isolate the preamp and power stages) then it shouldn't be an issue. Link to comment Share on other sites More sharing options...

No, amp does not have pre-in so cannot do this. I would be connecting to one of the standard analog inputs. Thanks Link to comment Share on other sites More sharing options...
Owen Y Posted October 8, 2009 Share Posted October 8, 2009 Hmmm... you COULD connect a 2nd preamp into say a Line/Aux input, but the signal would still be going thru the existing preamp/vol control etc. So, what you'd doing is adding a whole extra box of (tube ) electronics. However, it MAY give you an acceptable sonic result... theoretically must be degraded to some extent, but... the tube part may give you something attractive... acting as a a sort 'filter' in front.

cortisolman Posted October 8, 2009 Share Posted October 8, 2009 It could be an idea to get an electronically savvy friend to look at your amp and see if the pre and power are separate, and then patch your own connection through. Link to comment Share on other sites More sharing options...
tamarillo Posted October 8, 2009 Share Posted October 8, 2009 there is a relatively cheap hybrid power amp on TM that may be a place to start your valve journey - http://www.trademe.co.nz/Electronics-photography/Home-audio/Amplifiers-tuners/auction-246678431.htm Link to comment Share on other sites More sharing options...
