I have just bought a Rotel RB980-BX power amp and only have a Tandy reciever as a pre amp. My idea is to make preamp outs on my Pioneer A400 integrated as I think the preamp section on this amp should be pretty reasonable and has a MC phono input which the Tandy lacks. Has anyone done this to their A400 or other integrated and what were the results? Also can anyone point me to the point on the circuit (link below-the A400 circuit is from page 6, the A400X precedes it) where I could tap into the preamp section? Thanks.

metako said:Thanks for the answer. Yes I'd like to use the volume control. I dont think the tape outputs will allow this.
In that case, you must take the signal after the pot...
metako said:sorry for my extreme ignorance but I cant seem to find the pot on the diagram. Can you point me to it? And which wires would I use there? Thanks again.
The pot is VR701 and you must use the wires that connect to R201/202, respectively for L and R...
metako said:I can see it now. Thanks very much Tube_Dude. Does this mean that downstream of R201/202 is the power amp section, to which I could connect another set of phono plugs and use as a seperate power amp?
metako said:Started this a while ago and ready to finish it. Can anyone tell me the best place to take the earth from for the pre outs and power ins? Is it OK to just take them from where the pot is earthed on the board?
Yes!
I finally finished this little project! I know its very basic but I am very happy with the results, and so for anyone with an A400 here are some pics. Wiring is single strand .7mm silver with heat shrink insulation. It sounds brilliant and with the Pioneer as pre and Rotal RB980-BX for power it has, as I had hoped, the delicate, pure, expansive qualities of the A400 and the sheer power of the Rotel.
